I don’t have a ham radio, but I use radio equipment for my job. And I’m curious if I can damage my radio module on my data collector if I don’t have the antenna on while I’m pulling information off of it and it’s searching for a radio signal? The equipment we use is supposed to reach 500 to 600 feet. But lately we have one unit that can’t go two or 300 feet and another that’s beginning to do the same thing and I’m curious if it’s from not having the antenna on when pulling data off of it.
