[TowerTalk] XM240 element length question

[D. Drake]

Here's the SWR curve for my XM-240 Jorge. It may
not answer your question exactly but you can see
my results.  The antenna actually ended up
resonant a bit higher in freq than I tried to set
it for.

Hello

 

 

XM240 manual say about CW, MID and PH lengths to
make it resonant in 7025,

7125 or 7225 Mhz

 

 

What is the bandwidth? If I assemble it for 7025
Mhz, do you know SWR at

7.200 Mhz?

 

 

If I assemble it for 7.125 Mhz, do you know SWR at
7.001 Mhz?

 

 

Thanks,

 

Jorge
