I'm considering purchasing a 2mtr.& a 220Mhz (sma & bnc). From CheapHam.com. Models: Super Stick II & Super Stick III. Now, I'm concerned about the "stress" factor that these type of antennas would have on both type of connections. I always value the input/experience that any of you might have about issues of concern to me. Any suggestions/opinions & pros/cons for other options to consider? Thanks, 73
