Surecom SW33 Plus Handheld SWR & Power Meter Review

The Surecom SW33 Plus is a SWR and Power Meter specifically designed for use with handheld radios. Covering from 125-525 MHz it's the easiest way to check how efficient your handheld antenna is working but does it really work and is it worth the money?

Nice job reading the manual and understanding you need to hold the unit while taking swr measurements. Seen so many try to use it and not understand that then get puzzled when they get wildly inaccurate readings.

In order to get a more accurate SWR reading, I made a ground plane plate out of a piece of 8"x7" 26 gauge aluminum roll flashing. With a 19/64" hole drilled dead center, it fits perfectly between the double male adapter and the antenna you are testing. Using this method I got perfect SWR readings on GMRS channels with two different radios using my 771G antennas, confirming - to me at least - they are optimized for those frequencies while non-GMRS frequencies had higher readings.

Thank you for your video, it helps a lot. I have a somewhat stupid question perhaps, but I am testing an extendable antenna to see at what length the transmission is optimal, but the sw-33 itself measures +/- 3 inches, so do I have to deduct this length of the final calculation?

Great video 😍

Good day.

Thank you for the positive review. I'm curious, would this equipment be suitable for testing both my 25-watt and 45-watt base radios, or is it designed specifically for portable radios? Your clarification would be greatly appreciated. Thanks!

Mine only works for about 20-30 seconds max before it shuts off and needs charging again.
