If your unit uses a coaxial connector, then wire the coaxial connector to the load using
the shortest possible length of cable. For power levels greater than 1 kW cable length
should not exceed one meter. Use a coaxial cable with high voltage capability and
good thermal immunity. AE recommends RG 393/U, a coaxial cable with Teflon
insulation. Compared to conventional coaxial cable capable of operating at 80
maximum, this cable can run at up to 200
is important, as the heat generated by the losses of the connection plus the heat
transferred from the load is considerable.
If your V arioMatch match network uses a female 6 mm multi-contact high-current
connector or an M6 bolt,
wiring of the

wide is much better suited for this connection than a thick wire.

SHIELDING THE RF CONNECTIONS

Shield all RF connections to prevent RF radiation and to minimize safety hazards.
Shielding is also important to communication, as excessive noise can corrupt the data
packet and cause errors. If you are using a copper strap, arrange a good, well­
grounded shield around the copper strap (as you would with a
