Thanks guys, some great information here! Axeman, thanks for the in-depth yet noob-friendly explanation.
I’ve been reading about this, and watching youtube videos. I ordered some UFL to SMA pigtails (5) from the interwebs and they should be here today.
Does a 1/8th wave antenna work well? Or even a 1/16th for that matter? Or how much difference it there from that to a 1/4 or 1/2 wave? Or should I stick with the bigger one?
At 75Mhz (probably the lowest I have to go), a quarter wave I think is about 3 feet. So I wondered if cutting it in half for portability and maneuverability would be ok. I still will need to find some jacks and the thinner coax I guess to make the rest of an antenna. But will likely need to make a few different ones to experiment.
It would be cool if could have a group of different antennas and Lime could just pick the best signal for what you are scanning.
What would be the best kind of cable, jacks or adapters to put a wire or rod antenna on the SMA connections? I’m used to soldering and working with cable to make Tesla-based equipment.
I figure I can go to lowes and see what they have too.
The science of it is interesting, but not easy to find clear answers. I like research, but I’ve been too bogged down lately to do the in depth study I normally do. I wish it was easier. where you could just pick out what you need for X frequencies and plug it in.
Oh, before I forget, I saw someone had a big coil of wire as an HF antenna. There might have been two coils, zip tied together in a big loop each. Does that work? Can an antenna be bent or coiled up and still work well? That would save a lot of space.
