I got this from Digi-Key (http://digikey.com) as I said in my previous reply
to Chuck. You need to buy both the antenna and the antenna base:
Antenna: ANT-433-CW-RH (http://tinyurl.com/6zg4uz)
Base: CONREVSMA004 (http://tinyurl.com/6qb3fv)
Beside making your remotes much more pro looking than if using wires, it is
much more rugged. There are other variants to this antenna modification if
you don't want to put any money into it, or if you don't want to have some
wire sticking out of your transmitter. Here is one that I would e.g.
consider: http://tinyurl.com/4kugtp
I have had not autofiring problems with the 16channel versions, and after
this antenna mod on the 4 channel units, they have behaved much better than
before.
