Here's a cheap trick that works well for attic mounting of VHF/UHF antennas.. This is my back up antenna I use when I got my outside antennas tied up with a repeater I'm building or when the thunderstorms are getting a little too close.
The antenna you see is a 6m/2m/440cm tribander (same as I use on my vehicle, installed in the attic. Remember from our discussion of CB antennas, that mobile antennas must have a counterpoise or "mirror" made of metal to reflect the "other half" of the 1/4 antenna to make a complete 1/2 wave vertical dipole.
I used a 4' square piece of sheetmetal with an SO-239 bulkhead UHF connector bolted in the center and the particular antenna just screws on.. Nothing real critical about the size of the sheet metal piece other than it would be a good idea to make the width at least 2/3's of the antenna's height.
The feedline is soldered to the connector on the underside of the sheetmetal and can be seen coming out from underneath on the left side. Closets are handy places to bore a small hole to run the feed line up into the attic..
