Good advice, Peter. Nothing less than LMR600 should be used for feed lines at 2m and 70cm. Naturally if you're really interested in VHF/UHF work, some sort of hard-line is better.
Another thing I recommend: Never, ever use a regular multi port switch box for VHF/UHF. Make one your self using coaxial relays. You can switch 4 antennae with two relays. My installation is configured for 2m with stacked horizontal loops on the NC side of the relay and the 18 el Yagi-Uda on the NO side. The 70cm system is done the same way. My relays are inside a military ammo can on the mast of the tower. The ammo can and relays cost less than a store bought switch box. 73, Tom Amateur Radio Operator N5GE ARRL Lifetime Member QCWA Lifetime Member On Mon, 21 Jan 2013 16:13:30 +0000 (GMT), Peter Torry <[email protected]> wrote: > > > > >Phil, > >I use a K3 with internal transverter for 2m driving a LDmos power amplifier to >good effect.
