It is a 1/2 wave on 2 meters providing 3 dB gain and a 2 5/8 wave on 440 MHz providing 5.5 dB gain. VSWR 1.5 : 1 or less. This antenna can handle up to 120 watts. I installed this antenna on my Motor Home because it is ground independent. It had 1.3 : 1 or less on both bands.Re: What did you do to your Class A MH today???Sadly I put it to bed for the winter.Looking forward it spring so we can have some great adventures.
