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?

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!

Thanks for the comment! The unit is really designed for testing handheld radio equipment due to the SMA connections used on the unit but there is no reason why it shouldn't work for mobile radios with the correct adapters on each end of the unit. For example, SO239 to SMA Male. The unit is rated at up to 100W so should be fine but if you're testing without a proper antenna connected you would need to purchase a larger dummy load than the one provided in the package as this is only for radios up around 20W. Hope this helps a little?

Good day. Don't know if I've made a mistake but I was using the SW-33Plus on my Baofeng UV17L and and a RH 770 antenna and it is gave me a reading of 4.22 on the SWR on the FRS frequencies. Is there something wrong? What would be its ecfect on my radio? Thanks and 73s.
