View Full Version : Measuring SWR with a Watt Meter

Howdy folks!

I got my hands on a Bird Watt Meter and a suitable plug to use for 2 meters and 50 or so watts.

I am using it to check the SWR on my Maxtrac/plumbers J pole combo in the garage.

I measured 41 watts output and 1.5 watts reflected.

I have 50' of RG-8X.

I used a constant of 3.1DB/100' for the cable.

I used this site to calculate the SWR and got 1.75


Is that OK? Does that all make sense?
