SWR Meter - Pencil Box
This SWR Meter is housed in a pencil box. The transmission line is a length of TV hardline. Sensing
lines are hook-up wires, run close to the centre conductor through longitudinal holes made in the foam dielectric.
A tuning indicator (salvaged from an old Philips transistor radio) is used as the indicator, along with a 47KΩ potentiometer for sensitivity adjustment.
