[TheList] Aerials

Thu Feb 8 21:02:58 AEDT 2018

I find a 1m whip to work sufficiently on 75mhz 140mhz and 480mhz give or take you get a ¼ wave on 75, ½ wave on 140 & 2 x full wave on 480.
As stated fine antenna tuning is only required for transmitting.
Cheers

Dear all,

This may seem a stupid question to some of you but I think it needs to be asked - what is the optimum length for an aerial for a scanner receiving VHF communications i.e. the ESA and ESB bands.

Obviously, it needs to be longer than a UHF aerial but what is the ideal length. I've used aerials of various lengths on my scanners and with VHF I find the longer the aerial the worse the reception after about two metres - in other words bigger is not better!

But I'm sure there is someone on here who can tell me the perfect length and the reason for it.

Cheers and thanks for your help.
