Forward and reflected power direct digital readout, without any calibration. NOTE: DOES NOT compatible with Digital Radio.Build in Frequency country. Interface (in and out ): SO239 - The SW-102S Digital SWR Meter is engineered for optimal performance within the popular VHF (144-148MHz bands) and UHF (430-450MHz bands) amateur radio bands. This is where it delivers its most accurate readings for Standing Wave Ratio (SWR) and RF Power output, essential for setting up and maintaining efficient antenna systems. - Low insertion loss (0.3 decibels or less) structure allows it to be permanently connected - Handheld Radio Users Note:Many handheld radios have a low-power ("Low" or "Eco") mode that outputs BELOW 0.5 watts. If your meter isn't reading, first check that your radio is set to MEDIUM or HIGH power. - Requires Minimum Power: For both the SWR and Power Meter functions to work accurately, the power meter needs a stable input signal of at least 0.5 watts. Maximum measurable power range up to 120W - NOT for CB Radio: This SWR meter is NOT compatible with CB radios operating on 27MHz CB channel frequencies. It is designed for higher VHF/UHF bands. Ensure compatibility with your radio's frequency range before purchase.Note: The meter can measure CW, AM & FM only, cannot meausre RTTY and SSB. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B01M7QPXEY | | Batteries | 1 Lithium Ion batteries required.

It’s accurate as I tested the measurements against another meter resulting in almost identical results. I love that it has the digital display so I’m not guessing trying to see the needle like they have on a lot of other meters. It comes with very straightforward instructions that make it easy to use. It’s important that you check the frequency it measures before you buy it. If your antenna doesn’t fall within the parameters of the meter, you won’t be able to measure rhe SWR of your antenna. They have several different meters with various frequencies. They’ve made it quite easy to connect your antenna and radio. This helped me fine tune my antenna so I can make more contacts with my hand held radio. This is great for checking an antenna when I’m away from home since it’s small enough to be portable. I continue to use it to check my homemade antennas as well as antennas that I purchased. ### ⭐⭐⭐⭐⭐ Great SWR meter *by on Reviewed in the United States February 12, 2026* This is a great SWR meter for 2 m 70 cm. It does a great job at power and SWR. ## Frequently Bought Together - Surecom Gam3Gear SW-102S SO239 Connector Digital VHF UHF 125-525Mhz Power & SWR Meter - Superbat UHF Male PL-259 to UHF Male PL-259 Low Loss Digital Coax UHF Jumper Cable (12" RG58) for HAM & CB Radio,Antenna Analyzer,Dummy Load,SWR Meter - XRDS-RF 50W PL259 UHF Male Plug RF Dummy Load, 50 Ohm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/35447198-gam3gear-sw-102s-so239-connector-digital-vhf-uhf-125-525mhz](https://www.desertcart.us/products/35447198-gam3gear-sw-102s-so239-connector-digital-vhf-uhf-125-525mhz) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-07*
