Really? Are you saying that I should have the antennas a
quarter-wavelength away from the wall? Or do you mean separation
between the two whips? The former would make them *really* prominent..
And it seems that the design of the receiver, when using them directly
mounted to it, wouldn't have them that far away from *anything*
(especially if it were rack-mounted along with other gear).. Also
possibly adding to the useful information is that the building is
stick-built, so there's no aluminum studs or anything to act like big
reflectors. Just a big metal-frame window. Anyhow, they are indeed
probably 1/4-wave (didn't measure, but looks right) with a 90-degree
bend into the BNC connector...I was hoping to just be able to get a
couple panel-mount BNC females to affix to the wall..
Thanks for the wisdom!
