I think this is a fantastic idea. Off the top of my head, I have two ideas for antennas we might want to build.I'm wondering if there would be interest in doing a "tech night" get together to make home brew antennas. Something that could be used at home but also packed up and taken to a camp site.
I tried both the stock antenna and a DIAMOND SRH77CA, no luck hitting the repeater. I am about 32 miles from the repeater which is probably just too far for my radio. If I drive to Bountiful it seems to work fine.
