I know very little about antennas, unfortunately. But I do know a lot of hams who practice using organized nets. I think it's more common in the HF bands than VHF/UHF bands.
VHF/UHF nets are fairly common in larger cities, particularly for the ARES/RACES members - in NYC, it's on the 147.00 repeater on Monday nights (I have not checked-in to the net in a year+, but used to be a regular net control operator)
