I want to check my VHF antenna's SWR before transmitting — does this meter show both power and SWR together?

Yes, the SW-102 displays forward power, reflected power, and SWR readings simultaneously on its digital display across the 125-525 MHz VHF/UHF range, giving a complete antenna system evaluation at a glance.

This meter has SO239 connectors — will it connect to my PL-259 coax and antenna without an adapter?

Yes, SO239 connectors accept standard PL-259 coaxial connectors directly. This makes the SW-102 compatible with most VHF/UHF antenna systems that use PL-259/SO239 connections without any additional adapters needed.

What is the maximum power level this meter can handle? I have a 50W mobile VHF radio.

Always check the product's specified maximum power rating before connecting a 50W radio. Exceeding the meter's rated maximum input power can permanently damage the instrument. The power range is listed in the product specifications.

Can I use this meter with handheld radios, or is it only suitable for mobile or base station equipment?

The SW-102 works with handheld radios, mobile transceivers, and base station equipment within the 125-525 MHz range, provided the radio output does not exceed the meter's rated maximum power input.

Does the SW-102 display SWR in real time while transmitting, or do I need to read it after transmission?

The SW-102 displays SWR and power readings in real time during transmission. The digital display updates continuously while RF power is present, allowing you to monitor antenna match dynamically without waiting for transmission to end.
