Re: 405-Line VHF Aerials in 2013
Sounds like utter rubbish to claim 6dB over an H. If that was the case the design would be widely used today. By simple theory you would need 4 times the number of elements to gat a 6dB increase = an 8 element (at least).
Around 1 dB over a dipole sounds about right. More or less a waste of time.
What is the gain of a 2 element (H)? You get 3 dB by doubling the field power at a distance point and a bit more because you are firing mainly one way. 4 - 6 dB is claimed.
