I've mostly been using a discone in the attic so far, but now I want to get proper antennas up for 2m/70cm and gmrs. I'll probably get common commercial vertical antennas. I'm not sure how much I really need to be worrying about them interacting, and since changing placement changes what sort of support system I need, which could change which antenna sizes I can use, I'm unsure about where to start.
So far I've been looking at:
- GMRS (50W) looks like most antennas are about 5dbi
- 2m/70cm (100W) - maybe comet gp-6 ? 6.5dbi on 2m, 9dbi on 70cm
How should I arrange these to avoid damaging one radio when transmitting in another?
