My Unusual DIY 500 Watt RF Dummy Load - Part 2

Описание к видео My Unusual DIY 500 Watt RF Dummy Load - Part 2

Let's test my DIY RF dummy load and find out how well it performs.
Please note I should have recalibrated the VNA when testing the 144/220/440 MHz SWR. This may have resulted in a lower SWR for these bands.

Below are some of the sources for parts I used.
