Mark,

Can't help much on the base station aerial. 1/4 wave with ground plane whips angled down should help radiate horizontally though. Higher you can get it the better.

We are running a mobile eftpos machine but have been for years.
What type of base station aerial would you recommend ?

Thanks
Mark

Mark,

Are you running GPS  or other computer type equipment also?

Sounds like you are getting some RFI from other equipment in the car. Could be coming in via the power lines to the radio or just radiating and being picked up by the receiver.

Hello All,

As some of you know I work for the taxi company here in Benalla.
We are having issues with our VHF radio's.
Was just wondering if some of you with more knowledge than I could offer some advice ?

The problem we are have is with receiving transmissions, a lot of static and a lot of times unreadable and yet transmission is fine. The radios run at 150.2 mHz. These issues are only over a distance of 3-5 km's.
We use to get 15 k +.
And have been getting worse over the last 6-12 months.

Cheers
Mark Goodley
