I've preferred homebrewed antennas because they are fun to build, usually less expensive, and work very well. I, however, received in payment for repairing some broken down porch steps an older Imax 2000. Because I can operate 17m - 10m SSB area without hitting the tuner button I keep it up. No typical GP 5/8 wave, nor any dipole, has ever provided the bandwidth the Imax2k has for me. Are there big losses because of that? Probably. I don't care. It is not on my checklist of needs for receiving or sending signals on those bands to be useful to me. I can't hear them then I don't miss hearing them. If I can hear them, I may key up and talk to them. It never disturbs my sleep at night if I didn't catch that slight signal from catdaddy out of boondocks bayou...
And I'm sure Catdaddy doesn't lose sleep over me.
