Hi Toni this is like the old days :-)) nice to have a chance to chat=
 again.

My thought is how far could you get say a loop away from the vertical?=
? if
it must be quite close you will need to detune the vertical during rec=
eiving
on the other antenna. When the boys here used the Decca mast they need=
ed a
big attenuator (40dB ish) just to lkill the noise so it didn not overp=
ower
the receiver front end. I think a couple of other stations using
"commercial" antennas have had the same problem. Plus the fact that if=
 they
have warning lights the chokes in the supply to the lights doent give=
 much
impedance at 136, might be ok at 500 but propably still a bit on the=
 low
side as that sounds like a MW mast ??

Good Luck with it.
