Mcbazel Surecom SW-102 Digital VHF/UHF 125-525Mhz Antenna Power & SWR meter

I was looking for a small, light, power meter covering 2m and 70cm for use at a portable station, to check the antenna and to set output power. This unit fits the bill very well. It is of very good build quality (exceeding my expectations, to be honest) and works flawlessly. The power measurements agree well with other meters, better than 5%, across of a range of levels and on both 144 and 432 MHz. I like how the most recent measurement stays on screen after the RF is switched off, useful if the meter isn't easily visible from the operating position. The frequency counter is a bonus, although I don't think I will make much use of this. It is accurate to all 6 displayed digits (i.e. better than 1 kHz). An interesting feature is the ability, via the menu, to adjust the calibration of power and frequency measurements, although this does not appear to be necessary. The use of N-type sockets instead of the cheap SO239 types should help to minimize the impact of having the unit inline, particularly at 70cm. I couldn't measure the insertion loss, but even though the spec says it is low, I will probably not leave the unit in line once measurements are made, as every 0.1 dB of loss in the antenna feed adds to the noise figure of the receive system. Overall, a very effective unit, ideal for compact portable station use, and good value for money.

Purchased this to go in my /P kit as it offered a compact solution. Item arrived next day from Amazon so full marks so far. Brief initial tests were conducted with the meter as received, on known VHF and UHF aerials and also on a dummy load. I would echo other reviewers comments in regard to display size, however as a spectacle wearer I had no major problem reading the info. The SWR readings compared with previous tests on my analyser were within tolerance and acceptable. Power readings were all tested at various QRP levels with a dummy load and gave a reasonable guide to rig output. Readings from the forward and reflected power can be manually tweaked through the software as can the frequency displayed. My unit was supplied with a euro 2pin 1 amp charger as well as a UK type charger, and two N' type plug to SO-239 adaptor plugs. All in all this should serve my requirement very well and while it is certainly not Lab quality spec it is not a Lab quality price! As for durability, that remains to be seen, but unit is manufactured in a robust metal case which looks like it will standup well to normal usage. Hope this helps with your purchase decision.

Excellent item... Good and easy to use.

Seems to do what it says on the box. Display dim, cluttered and lacking contrast. Certainly showed my antenna problem. Doubt if it's super accurate but for the price it's great for most day to day and troubleshooting applications.

This is very good: small and bright to see in daylight

I was updating my Amateur Radio Satellite ground station and test equipment in order to try and receive from QO100 ES'Hail Geostationary satellite. I ordered several test equipment for 144 MHz, 70CM, and 23CM, including transceiver, Standing Wave Ratio (SWR) and output RF Power meter. Fast order to next day delivery. Excellent equipment for a reasonable price 👏.

Very happy works perfectly

It works but…..I still double check with an old swing meter lol . It very easy to use, set up. ( turning on don’t forget hold power button down for 5 seconds before you return it as not working ! ) Easy clear to read. Handy power meter and frequency read out is accurate- so yes recommend it
