I've been stuck in town, away from my shack in the hills, and not had the chance to do some antenna projects I've asked advice about previous. But, playing with some mobile whips when I get the chance had me curious about a few things. Playing around with my 102" whips, one with a spring for CB length and the other at regular 10 meter length, I was surprised at how good the 102" whip was for broadband reception, but the 108" length was not. If resonance isn't important to reception per se, why does the shorter whip do better than the long whip? The 102" was good through the phone parts of 20, 40, 80, and even 160 meters (in the middle of summer, no less)! Last night I could read 40 and 160 very well. The 108" electric length was not good at anything. I've talked to others about the possibilities of these whips for out of intended band operation. Indeed, I was able to get a good SWR on 20 meters with the 102" with a manual tuner, but how good is such a compromise setup, really? 20 was dead last night so I could not give it a decent try yet. I tried the 108" length with spring on 50 meters, where it should be half length, and I didn't seem to get anything that on the manual tuner that would work. I suppose there is something I'm missing. I also asked about a compromise vertical antenna for 160 meters recently, with good reply. I've asked on another forum, and also DX Engineering. Suggestions seem to be in favor of an inverted L antenna, even though I have the space for a full dipole, but not the ability to put it up at half wavelength height. A bit long winded, but any insight would be useful. Thank you.
