We have this special Alfa-branded 7 dBi directional panel antenna. This antenna has an RP-SMA connector and can connect to many Alfa Network brand wireless USB adapters including the AWUS036H 1000mW USB long range Wi-Fi adapter. This will also work with other brand Wi-Fi adapters and routers/APs that have an RP-SMA port. This item is brand new. They come to us in OEM bulk packaging from Alfa so there is no retail box, it is just the antenna itself as pictured. Also there are no instructions, and that is because none are needed- you just screw it on to your Wi-Fi adapter's RP-SMA port and you are all set to go. If you are also in the market for a long range Wi-Fi adapter, we do have this antenna bundled with an Alfa 1000mW AWUS036H adapter here.

Directional vs. Omin-directional antennas


The above image is not a precise scientific comparison drawing, but an illustration to show in a general sense how the two antenna types compare. This 7 dBi gain panel antenna is directional. Antennas that usually come with Wi-Fi adapters are often omni-directional. Omni-directional antennas can detect signals from multiple directions. Gain is not concentrated in one particular direction. Omni-directional antennas work best when you are mobile and do not know where signals are originating. Directional antennas concentrate gain in a particular direction. While the antenna does not need to be in a perfect line of sight to the signal, it needs to be pointed in the general direction. Due to the way antennas work, directional antennas can pick up signals that are the in the opposite direction, but they will be weaker than if the antenna was pointed in that direction. As our graphic above illustrates, each antenna type has an advantage over the other. That is why it is best to have each type, so you can use the antenna that is best for your particular needs. Because directional antennas work best in the direction they are pointed, in many cases you will detect more signals overall with your omni-directional antenna, but find that your directional antenna may get stronger signal strength to signals it is aimed at, and it may also detect additional signals in the direction it is pointed, signals the omni cannot see.

Additional Features:

- Antenna is rotatable to you can adjust the direction
- Engineer-tested compared to other directionals on the market to ensure excellent performance
- Alfa-branded, the trusted name in wireless networking- not a generic antenna
- Complies with 802.11g standard for 2.4Ghz Wireless LAN
- Contains RP-SMA antenna connector
- Works with all 2.4 GHz Wi-Fi devices that have an RP-SMA connector, not just ALFA brand ones


FAQ- some common questions about Alfa 7 dBi directional antenna kit:

I pick up 6 signals with a 5 dBi omni-directional antenna I have but only 4 signals with this 7 dBi panel antenna- is something wrong with the panel antenna?
-The panel antenna is a directional antenna that concentrates gain in the direction it is pointed. It does not pull in signals equally from all around, but should pull in better range and signal in the direction it is pointed. So you may see more signals overall with the omni, but the directional one will help you get the best signal to one in particular.


Whether I use a 5 dBi omni antenna I already have or this directional one, I see 3 signals, and all of them have the same number of bars in Windows. How can this be?
-antenna placement is very important. Wi-Fi signals bounce around and can be impacted by invisible interference (noise). Also note that when using a utility that reports signals as 4 or 5 bars, each bar represents 20-25% of signal strength. So one antenna may be pulling in the signal 15% better than the other, and yet the difference in bars may be only 0 or 1. We recommend using more detailed programs for precise signal strength analysis. Our support staff has over 100 years of combined Wi-Fi and antenna experience, so please contact us for help with antenna placement and details on what programs to use for signal strength testing.


How far away can I pick up signals with this compared to a standard antenna?
-For this question there is no exact answer. Wireless range is an imperfect science. The range you get with any adapter will vary markedly depending on the strength and quality of the wireless access point being used, as well as obstacles and interference in the area. Keep in mind that interference can often be invisible. This antenna is a directional antenna that should give you a better signal and longer range to a particular signal when it is pointed in that direction, vs. an omni directional antenna of the same game. Things such as antenna placement (even just a few feet) can have a big impact on performance. As always, if anything seems off about the product performance, please contact us directly for one on one assistance. If you are trying to pick up signals from far away, and are not sure this will give you enough range, please contact us with details about your situation and we may be able to offer an opinion.




Orders will generally be shipped the same or next day after payment is received. Periodically if we are experiencing unusually high order volume, your order may not be shipped until the second business day after payment is received, but this is not usual. We offer both UPS and US Postal methods of shipping as described below.

US 50 States + Puerto Rico: FREE US Postal First Class Mail. This includes delivery confirmation and insurance. According to the US Postal Service, First Class takes an average of 3-7 delivery days to arrive. This is not a guaranteed transit time though, it is just an average delivery time (internationally First Class can take 2-4 weeks, international buyers please read all international shipping details down below).

US 50 States + Puerto Rico: $4.00 US Postal Priority Mail. This includes delivery confirmation and insurance. According to the US Postal Service, Priority Mail takes an average of 2-3 delivery days to arrive. This is not a guaranteed transit time though, it is just an average delivery time.

US 48 States: $9.50 UPS Ground Service. This includes insurance and tracking. This rate is only for bidders in the Continental US. We do ship to Alaska/Hawaii and APO/FPO but it must go via the US Postal Service so please take a look at a US Postal option. If you need the item shipped via an expedited method like 2nd Day Air, please inquire with your zip code for rates before bidding. UPS Ground can take from 1-7 days or longer depending on your proximity to our shipping location which is in Florida. UPS can take longer than US Postal Service Priority Mail, but UPS tracking tends to be updated more often than Postal Service tracking, and UPS tracking typically posts an estimated delivery date online within 12 hours after shipping, where as US Postal Service tracking does not.

International Shipping Rates & Customs Duty Information: We ship worldwide via Standard First Class mail. This method is $7.75 ($5.75 for Canada) but can take 2-4 weeks or longer to arrive. This is primarily because the item can be held at customs for inspection for a long period.

*
Import duties and taxes are not included in the item price or shipping charges. These charges are the buyer's responsibility. Please check with your country's customs office to determine what these additional costs will be prior to bidding/buying. These charges are normally collected by the delivering freight (shipping) company or when you pick the item up- do not confuse them for additional shipping charges. We do not mark merchandise values below value or mark items as "gifts" - US and International government regulations prohibit such behavior. See full International terms and details in the "Overseas" section at the bottom




United States bidders & International bidders can pay with PayPal. We also accept direct credit card payments (from US bidders only). After the auction is complete we will send the link for direct credit card payment.

GENERAL NONPAYMENT POLICY- Remember that your purchase is a contract to pay for the item. Please don't click the "Buy Now" button unless you will pay for the item. Payment is due within seven days from the end of auction. If you have a problem completing the auction, please communicate with us. Please make sure this is the item you want before buying as once an auction is won or purchased unfortunately because of nonrefundable eBay listing and feature fees we are unable to accommodate cancellations (exception- if you buy the wrong type of adapter for your computer, such as a laptop card when you meant to buy a desktop card, we can switch your order to the correct type).




The following is our return policy. We are not able to make exceptions to this policy so please read carefully before making a purchase. While we would greatly appreciate your business, if you are not in full acceptance and agreement with these terms unfortunately at this time you are not eligible to bid or select "buy it now" on the auction. Bidding or selecting "buy it now" on this or any of our auctions constitutes full acceptance and agreement with all of our auction terms including our return policy.

At Rokland, our products are guaranteed to work for 30 days. Additionally, we want customers to be able to return products that they don't want, don't like, or did not mean to buy. That said, we do incur costs for each return, such as the nonrefundable eBay listing and feature fees. If an item returned was new, we must resell it for much less money as a used open box item. Therefore, we charge a minimal 10% restocking fee on all returned items (new and used), except for products that test defective upon receipt back here. We believe this is a fair policy as most eBay sellers do not allow for any non-defective items to be returned at all, and the ones that do typically charge a 20% restocking fee. Again, this 10% restocking fee will be applied to all returns except where a product is reported to us as defective and tests defective upon receipt back here (if the product you return is defective we can send a replacement at our expense or issue a refund of the item price, whichever you prefer). A restocking fee WILL be charged even in the event a product does not work on your PC due to incompatibility or a conflict with another piece of hardware on your system, so long as the product is not defective. We can work with you to troubleshoot the problem if you have any difficulty getting it to work. We will not charge a restocking fee if you wish to exchange a non-defective product for something else, however a new shipping charge will apply for the new shipment.

While we would certainly appreciate your business, if you feel that a restocking fee would not be acceptable in the event you want to return a non-defective product to us, please do not make the purchase. If you do wish to return a product, please contact us for an RMA number and return address instructions. In addition to the restocking fee (which will be deducted from your refund), shipping and return shipping expenses are not refundable under any circumstance unless we ship you the incorrect product. In the event we send the wrong item, we will send the correct one to you at our expense and also reimburse you for your return shipping of the incorrect product.

There are no other warranties on this auction, expressed or implied. The exception to this is if the description states there is a manufacturer's warranty. In this event the item should be returned to the manufacturer in accordance with that warranty if necessary.




1. Customs duty and tax: Many countries will charge the recipient import tax on items purchased on eBay. We do not have knowledge of which countries charge tax and how much it could be. Customers are advised to contact their local postal or tax offices prior to bidding. Rokand is not responsible and will not reimburse international buyers for taxes charged on delivery. Rokand cannot mark items as gifts, lower the value of the goods on the customs form, or engage in any other modification to assist in the lowering or elimination of valid taxes.
2. Insurance and proof of shipment: Items sent outside the USA are insured. US Postal Regulations state insurance covers only the cost of the product, and does not cover the shipping charge. When you inquire for shipping rate quotes, we will advise you of the average time frame for delivery. If your product has not arrived within 30 mailing days of shipping, please contact us so we can trace the package for you. All parcels are sent with tracking and tracking information is provided to the customer at the time of shipment. If your package is lost in transit, we will file an insurance claim on your behalf. The US Postal Service requires that all insurance claim filings include a signed letter from you, the recipient, stating you have not received the parcel shipped to your address. This is a requirement and the letter can be faxed to us, scanned and emailed, or sent through Postal mail. We cannot issue any refunds for lost packages or ship any replacements without this letter. If you select a replacement, we will pay to ship it to you. If you select a refund, you will be refunded only the price of the product, as noted above US Postal Regulations do not allow us to insure the cost of the postage.
3. Returns: Buyers outside the USA may return products in accordance with our above advertised return policy. It is important to note that shipping and return shipping are NEVER refundable, with the sole exception of a case where we ship the wrong product (example: you buy a wireless adapter and we send a keyboard by mistake).
