[ICOM] AH-4 help

Larry:
    Rather than shorten the antenna up, why not just fold it back 
towards the ends and it should still work ok.   Fern

My thanks to all who made suggestions. I'm only
considering the AH-4, and now other models, for
my situation. The biggest negative with the AH-4
is that the antenna wire would have to be
directly above the power lines that feed the next door neighbor.

I'm considering mounting a mast on the roof using
a suggestion I found on eham.com. The guy came up
with the idea of sliding some Sched-40 pvc piping
into a breather pipe on the roof. I could then
use the dipole attached to mast. Of course I'll
put guy ropes to the roof facia for stability.

My antenna is a 90 foot B&W wide-band folded
dipole which has been very reliable for me. My
roof is only 62 feet so I contacted B&W and
queried them about reducing the length of the
antenna. Their response was quick & the only
affect of shortening the antenna is the raising
of the lowest frequency of operation.

Again - thanks
