Um...
Is the potted plant an indication that the Jampro antenna can do better
in a high-foliage environment?
And I don't see anyone hanging from the ERI antenna, either....
here's a sidebar -
IF it weren't for wanting to go with circular polarity...
why not use a batwing / superturnstile antenna?
Seems like they're within a dB or so of true omni, and are definitely
broadband enough if constructed right (I mean, if they handle an entire
6 MHz TV channel with reasonable flatness...)
And they avoid the pattern distortion that a pole or side-mounting
introduces on almost every other antenna, since the mounting pole is
"inside" the antenna...
I do note that not having a significant vertical radiation pattern is a
shortcoming...
