Subject: Sigma 40XK on 40 and 30M
Author: Rich Holoch <rholoch@attbi.com>

I have the 40M coils on, and it works very well on 40M - at least 2 S units
consistently on DX stations (receive) better than my 88' doublet. It does
tune up on 30M, but I noticed that performance is maybe the same as the 88'
doublet. It sure does seem like the coils at the antenna are critical for
performance.

I will only be using this antenna for 40 and 30M, so I am wondering if I can
put the 40 and 30 meter coils on - in series. What would happen to the
performance? If this doesn't work - what might (some kind of tapped coil
arrangement)?

I know I can play and try these things - but its raining heavily today, so I
can only think about experimenting.

73,
