Right antenna?

[A Thompson]

Hi All,

using an antenna that is kind of a wire type with a sort of inch or so
diametre x around 2 inches high
base on it.

The reason for this post is that using the PWD program on 148.**** MHz we
can only get around 93% at
the best of times & down to around low 80s% RX when cloudy.

Scanner has discriminator circuit, so I was wondering if that antenna is
more for UHF as I thought the 148.0000 is
more a VHF freq?

Would that sound right?

Any help appreciated.

cheers

Adam

ps: maybe a Discone will solve all?

I think that's right. Certainly 148.000 MHz is VHF

what you need to do is work out the 1/4 wave length of the freq you use
and make a wire antenna to that length

there are plenty of plans on the internet for simple ground plane single
frequency VHF and UHF antennas
using the SO359 base and some ordinary copper wire

simple and cheap

also the formula for working out freqs in metres or feet is easy enough
to find on the net as well
