[TowerTalk] More questions - wired wireless antenna switch

[Pete Smith N4ZR]

This is further on the subject of the 315 MHz 8-position 
remotely-controlled switch that I'm trying to adapt to switch my RX 
antennas.  I have the two "couplers" rigged to couple the VHF to the 
feedline and pick it off at the other end.  However in examining the 
relay unit I see that the antenna for the receiver is a 13-turn coil of 
~#24 hookup wire wound roughly to 3/8" ID.  It seems to me that such a 
coil might have a fairly high reactance at 300 MHz, and yet when I use 
the unit in open air, the relay unit switches reliably out to about 200 
feet, so it can't be too bad as an antenna.  My simple-minded question 
-- should I uncoil the antenna and see if it can reach the whole 300 
feet without coupling to the coax?  If I'm using the "wired-wireless" 
method, should I uncoil it before connecting the free end to the 
coupling loop?  The loop, per earlier advice, is about a 1" length of 
hookup wire laid next to the center conductor of the coax (shield removed).

Thanks for any advice.
