Hi all

I'm looking for some pointers on making a mobile antenna for PMR 446.
I've got the mag mount and cable but what length should i make the whip.
Should i make it a quarter, half, three quarter, five eighth or full wave?

The easiest is 1/4 wave, about 6 inches long. No coils, caps or matching.

Hi BigTone

That Sirio looks the part, and if i can't build something out of the bits n bobs i've got then i will go down the buying route.

Cheers
