Gale,
In the same tower? I always assumed that 15-20 ft of separation would be
enought even for the 15/40 combination.
you are saying is not? What was the separation?
I have a force 515x about 18 ft below the xm240, SWR is great but
performance is not at par, my skyhawk tribander kills it
any day on 15 and they are about the same height. Maybe thats the reason.
Thanks
Felipe
