we are using a Comtac Modbus Bridge. As you can see, it has an external antenna.
I was wondering if it makes any difference if we lay the device on some board (antenna horizontal) or mount it to a wall (antenna vertical)? All the Gateway antennas are mounted vertically.
I tried to do some research on that topic but found very little useful about it. My radio knowledge is too limited (yet, of course, working on it ) to really figure it myself. Does someone have some information or experiences regarding this?
Thanks & best regards
