I wish I could afford something better, but on my budget, and with two kids
and all the bills that go with it, not likely. Hence why I get into these
positions. The only new antenna I have bought in something like five years
was the 6m yagi I just got, and it's not a hygain or cushcraft, its an Arrow
Antenna, and if they had a 8el or larger 2m yagi I would be buying it in a
heartbeat. Their antennas are built to last.
