I posted over christmas a question of gamma matching, thanks to everyone for
the replies.
Could anyone advise me about top loading when 4 wires are use as an alternative
to 2 with this type of antenna. My present antenna is 82ft vertical with 4 top
lading wires each 35ft long, I have been told only 1 wires counts as the
loading/lengthening on this type of antenna which I dont fully
agree/understand. Is it not that a 2 wire tee you calculate the missing portion
of your vertical lets say I needed 127 ft for 1.83mhz and my vert is 82ft so
45ft too short, so lets say 60% of 45ft = 27ft I would need 2 top wires 27ft or
maybe 70% of 45ft = 2 x 31.5 ft.
Am I on the right lines, what if I use 4 wires the reason been its better for
guying and I thought the 4 shorter ones mean less cancellation of the vertical
radiator!! Obviously I can use 2 rope for the missing guys but I thought 4
wires may be better
I have not seen any info on using more than 2 wires at least not unless we look
at a horizontal capacity hat constucted with rods and wires.
