Personally I would not use a long telescopic when out & about. They are a heavy antenna & put a strain on the BNC.
I use my long telescopic exclusively for use when the radio is standing in a corner with the antenna supported.
I use a flexible whip for portable use.
What frequencies were you listening on?
Were you doing band scans or listening to pre programmed channels.
The reason you heard nothing could be multiple.
You could have been listening to the wrong frequencies & maybe as they were in the rank they were talking to each other face to face, rather than over the radio? Also is it possible that they do not use radios but mobile phones instead?
