Pure. Simple. Innovation.

The RS-50M is the easiest to use VHF SWR power meter. Designed for marine VHF, easily test your VHF radio and quickly determine if there is an issue with your radio, a cable segment, or antenna that is preventing you from transmitting to maximum range. 

All Digital. No-Nonsense.

The only all-digital SWR tester specifically calibrated for the marine VHF band. The RS-50M shows you how much of your radio’s power is leaving the antenna as radio waves (FWD), and how much is being reflected back (REF). With the help of the RS-50M, you can track down and eliminate issues that are preventing you from getting your maximum range.

 

Use two triple-A’s or plug into a micro USB cable for continuous power. With a backlit screen and one-button operation, the RS-50M defines ‘worry-free’.

The RS-50M is now available through Amazon bundled with a convenient 1 metre male-male co-axial cable, or alone! You can still purchase the RS-50M by itself straight from CTEX at the shop.
