SW33 VHF/UHF mini Power & SWR Meter Radio portable handheld ham Black US

Nifty little thing. I would prefer the screen stop at SWR or power for at least 3 seconds. Great batch of adapters. Turns out my dipole has a terrible SWR. The UHF/VHF whip is much better w/ the handheld.

I received this today. On opening I found several adapters for SMA and BNC included and a 50ohm Dummy Load. So this was perfect for testing handheld radios as I could test the meter and using the dummy load test the power. So I set out testing the antennas of 8 BF888 radios. Wow, of the 8 only 2 had an SWR less than 19.9. I tested 2 new 14.5" antennas and they were 1.2 and 1.3. Tried a 7" and it was 15.0. So now I am replacing all of my antennas with the 14.5 since they are perfect for my own repeater. So glad I finally got this.

Don't trust it, can't be calibrated, also tried several reputable branded antennas (Nagoya, Smiley, Powerwerks) many come back as a 19.9 including a smiley antenna that's a 470mhz 5/8 tuned antenna. I used a Radioddity GD-55+, TYT TH-UV82000 and DM-UVF10 as well as a Retevis RT1 every antenna on every radio had a 19.9 SWR from 440-470mhz!

PROS:- Simple to use- Includes a wide variety of adapters- Small and well builtCONS:- Readout jumps too quickly between Power and SWR- No calibration option of any sort- Questionable accuracy of measurementsAfter testing it out on a variety of different handheld and mobile antennas, I have some doubts about this device's accuracy! Some well known and very good antennas from the Nagoya line for example, have shown an incredibly bad 19.9 SWR, which I have difficulties believing, since they work perfectly for both reception and transmission and in actual usage provide a much longer range than some of the stock antennas that came with the radios, which indicated much better SWR ratios with this device. So, I have some doubts... :-/

I have used this several times and it works fine. I do not have any high-end/high-dollar equipment to check this against for absolute accuracy, but for my purpose it seems to verify the antennas that I have built. I will design and model the antenna in software first and then build to the specs given. I then use this to do the "reality check" and fine-tune the SWR. I can say that the end results are pretty close to what the software predicts for SWR readings/ranges, so it seems to be accurate enough. I feel very comfortable using an antenna that I modeled, built, and then tuned and tested with this meter.

The instructions are comically minimal. I suppose if you have used one before maybe it doesn't matter but the text never even mentions turning it on.

Seems to do exactly what it's supposed to do. Charged it up with the included USB charger. It came with male/female SMA adapter AND male/male SMA adapter, in addition to male SMA to BNC. The male/female SMA adapter allowed me to screw it right into my UV5R, and the other end to my Comet SSB-224NMO with Diamond K-400 trunk lid mount. Got a 1.07 SWR, with 5.8 watts at 146.52... Have nothing to compare it to, but assuming it's accurate, it's going into the glovebox with a happy buyer.

This unit works GREAT. It is nice to not have to interpret a meter. It came with several SMA adapters for other RD connector types (BNC, UHF, etc.) and a 1/2 watt 50 ohm SMA dummy load!

Produit conforme et livré avec plusieurs adaptateurs et une charge fictive de 5w.Les mesures semble fiable. Le produit fait sérieux avec sa carrosserie métallique.A noter qu'il n'est pas capable de mesurer du DMR !La multitude d'adaptateurs, la charge fictive, la prise chargeur Europe et UK sont inclus.L'ensemble est peut être un peu cher (Actuellement 46.81€) mais complet.

No muy clara las medidas que da falta más información. En otros países trae más piezas. Colgar video en otros medios.

Swr を測ったところ 誤差が多くて 使い物になりません。 10%の誤差は あることがわかりました。

je viens de le recevoir il s'allume bien pas encore testé mais semble très solide ce n'est pas un jouet en plastiquey a plein d'adaptateurs avec ce qui n'était pas noté je crois dans le descriptif, et c'est un +++je joint une photo de la total

Comparé à un Diamond Sx400, les valeurs sont les mêmes et pour beaucoup moins cher. Plutot dédié à la mesure sur des pockets vu les prises SMA on peut néanmoins l'utiliser avec adaptateur PL. Bundle complet, cables adaptateurs, livraions expresse. Rien a redire !
