Home Brew Remote Matching Network is controlled by 8 relays, one for each band. The components are quite robust.

At 500w pep there really isn't any sense of heating except for some minor warmth in the Low Pass toroidal choke used on 75mtr (with 1900pf).

The parts chassis simply drops into the watertight enclosure and is mated with 4 connectors (2 banana plugs, 1 lug and a 9 pin Molex control cable connector).

The relays were modified to bring the 'common' out through the side of the plastic to avoid the parasitic capacity to the relay frame.

The gray pipes are slip-on's to cover the external connectors and cables.
