Hi Tom

If you really feel like not spending money on a SWR meter you might like
to try the horrible but simple approach of making one out of a piece of
RG213 with the PVC stripped off, and thin teflon wire pushed under the
shield in the same mechanical arrangement of a SWR meter. A couple of
shottkeys, capacitors and resistors and you can read VSWR on a multimeter!

I'd even venture to suggest that replacing the line section in a CB
meter with this arrangement would yield a much more useful higher
frequency device. (And use BNC's or N sockets...)
==================================
Instead of using RG213 coax I would use a short piece of 75 Ohms coax
(here in the UK used for sat dish feeder) with air gap dielectric .
The 10 mm (3/8 inch) OD variety is particularly suitable .
Without removing the outer sheathing a bare or teflon insulated wire can
be readily pushed through.
