Title: Installation of MFJ 1782
Post by: N4NOY on March 24, 2003, 11:44:46 PM
Hi folks..

I have purchased a Super Hi-Q loop antenna from MFJ to install in my attic (antenna restriction hell). The floor of the attic is at least 20' above ground level and I'm certain I can get the antenna at least 5' above that on a mast. There are some foil wrapped flexible ducts on the floor of the attic. Given this, would it be better to mount the loop vertically or horizontally?

I'd recommend you try both.  The MFJ-1782 is a magnetic loop antenna which behaves differently from a conventional Hertz antenna and the aluminum foil lined stuff may affect it in rather unpredictable ways.

I've used the Super Hi-Q Loops before, and own one for portable/camping etc. use, and always noticed it's not the height above ground that matters, it's how "clear" the antenna is from surrounding objects.  Mine works better two feet off the ground but in the clear than it does fifty feet off the ground but surrounded by building walls.
