[TowerTalk] elevated short vertical dipole orquarterwave monopole?

[Jan Erik Holm]

Strange. I´ve used gamma matched yagis for 35 years
or so and also used (at times) very high power, never
had a failure or any problem with it.
Sure a gamma match isn´t a perfectly balanced feed
method but IMO it´s simple and reliable.
