[Antennas] J pole horizontally polarized antenna

Tue Jun 8 10:07:17 EDT 2004

I have been asked to construct an antenna for a small community TV
transmitter somewhere in Africa on our channel 7 (174-180MHz). The J
pole or super J pole looks like a good candidate, but I believe it is
vertically polarized. Is there any way to make it horizontally polarized
(or elliptical for that matter)? Any way to electrically adjust the down
tilt? I am considering using soft copper tubing of ½” or 5/8” so it can
be rolled up in a suit case and carefully straightened out on arrival.
Any thoughts or suggestions would be welcome--other antenna types,
calculation software, construction ideas, etc.
Thanks,
