Big HF load

It’s based on a copper plate, big old whipped aluminium radiator and two 100Ohm resistors, 800watt each.

Links to the projects + some videos.

New JLCPCB order received.

After testing it I will share it on EasyEDA website.

Longer telescopic part for vertical antenna — better SWR on 40m and 20m without a coil: Copper plate for 1.5kW load: Resistors

JPC-12 antenna (looks like it’s a wrong case and jpc-7 is a dipole with the same base), waiting dry weather to test

It’s build from 250w 50Ohm resistors.

To not damage it in the backpack.
