Default Receiver with SMA connector?

Has anybody attempted to remove the wire antenna(s) to their 2.4ghz receiverand replace it with a SMA connector or any other connector with allows you to put a pole antenna on it?

If you are talking about 72Mhz, I actually bought a Deans Whip Antenna, but never used it. You have to shorten the existing 36" antenna and solder it to the post on the base of the Whip Antenna. I have seen it used, effectively, on numerous RC Jets, especially ones from Europe. Other companies make these, as well.

My fault - You did say 2.4Ghz - In the Spektrum world, 7ch Rx's and above have Satellite Antennas that you can place on extended wiring to give you more points to catch the signal. The Main and Satellite Rx's each have 2 antennas and the Satellite can be mounted in a perpendicular plane to the Main Rx.

I do not know what an SMA Connector is, but I would assume that a Pole Antenna would not work with 2.4Ghz since the default Antenna is so short to begin with. I have not heard of anyone using an External Antenna for that band. I am sure there are technical reasons why that is so.

Sorry when i said SMA connector i meant to say pole antenna, but i think your right there must be some technical reason why no body has done it.
