Nice tool, Jim. Much easier to use than CalTopo, but has the same limitation: According to both, I can't get to the club repeater from here, yet do it every day. RF can bend over hills, at least just

Dennis thank you very much for sending this out but if you had come across I just picked up what looks like a 35 ft TV antenna from 20 years ago it's got all the elements I would like it to be a 10 m

I’ve always tuned an automatic tuner with a low power, say 10w, cw carrier. Some tuners like the Yaesu tuner built into the Quadra amp take more, like 60w min. Dennis - WU6X

Orion, Thanks for the reply. When I first got the truck, I used a mag mount which was better than what I’m doing now but I’ve got a Crewmax and I roll the rear window down all the time in good weather
