Do you need mention but are you looking for variable or fixed direction
gain? Also is wave angle important - if so what angle?

Subject: [TowerTalk] vertical antenna advice needed
Hello folks,
I'd like to hear your opinions about this topic.
I am looking for an antenna (or more than one) for 10/15/20m that has the
following characteristics:
- vertical polarization
- smallest possible horizontal far field lobe
- "good" forward gain (at least comparing to a single element vertical)
- greatest possible front to back ratio
I was thinking about using:
- a tribander tilted 90 degrees
- 2 element end phased array of:
- vertical dipoles
- sitting on the ground verticals (with or without radials?)
- multiband verticals (using W9AD phasing line to switch between bands)
- 5/8th wave verticals (at least for 10m, it would be easy to convert CB
antennas)
- a 4 square
These antennas would be used for RX only.
Any suggestions, anecdotal comments, field experiments?
73 and thank for your time,
Felipe Ceglia - PY1NB
