We've got this special low-loss RP-SMA male to RP-SMA female extension cable designed to work with ALFA Network products. This is CFD-400 shielded. The cable is 10m long (a little over 32 feet) and can be used to put an extension between an RP-SMA antenna connector on a Wi-Fi USB adapter or PCI card and an RP-SMA antenna. This is a special low-loss cable (CFD-400 NL Low Loss 50 OHM). What does this mean? The antenna to which you will connect this to has a gain. Let's say for example you will be connecting this to a 12 dBi gain antenna. As the cable in between the antenna and adapter gets longer, you will experience cable loss, which is a drop in the signal gain of the antenna. With low quality unshielded extension cables, the huge drop in gain will mean a much lesser range. Our special low loss cable limits the cable loss factor and preserves the high gain of your antenna.
Why is this cable more than twice the price of our 5m CFD-200 extension cable?
It may seem more economical to chain two of our ALFA 5m extension cables together. This is not recommended. Our 5m cable has CFD-200 shielding, which is a good shielding for cables up to 5m length. For a 10m cable, CFD-200 is not the recommended shielding because of the distance. For a distance of 10m, to limit loss, CFD-400 is recommended. CFD-400 shielding is much thicker than CFD-200, and has several layers of protection. Because of this, the cable is 5 times more expensive to manufacture than the 5m CFD-200 cable. It is much heavier as well. Cable prices normally coincide with length, so a 10m cable will normally be twice the price of a 5m. But when you add in the thicker shielding, the cost goes up more. This cable is also five times heavier than our 5m cable, so the shipping cost is higher too.

Frequently Asked Questions:
1. I see 9m cables on eBay for only a few dollars with free shipping from China. Is that a better deal?
When you use a cable in between the antenna and the WiFi adapter, the gain of the antenna decreases markedly. This is a factor known as cable loss. The $3 and $4 RP-SMA extension cables that are in abundance on eBay have no low loss shielding. Using them will cause significant gain loss.To limit gain loss, you need a thick shielded low loss cable, from a trusted manufacturer. It has special low loss shielding to limit your gain loss.
2. I already have (or want to buy) an external antenna for my wireless adapter, and I want an extension cable so I can put my antenna further away from the adapter. How do I know if this is the right extension cable for me?
Check with the maker or seller of your antenna to find out what type of connector it has. As a rule of thumb, you want to get an RP-SMA male to RP-SMA female extension cable when the antenna you have can connect directly to the RP-SMA connector on your wireless adapter if you wanted it to. That would mean your antenna also has an RP-SMA connector, and this would be the right cable for you. If your antenna has another type of connector, meaning it is not possible for you to connect it directly to the RP-SMA connector on your wireless adapter, then please contact us so we can help you locate the right cable for your needs. Additionally, we always recommend to get as close to the length you need as possible. If you are only trying to go 10 feet, don't buy a 30 foot cable as you will have more gain loss than you need.
