I have built many different antennas for scanners. One that I built was made of twin lead for the Low and High Bands. It was simply a center fed dipole. It was mounted on a mahogany pole up a tall tree in the back yard. It worked wonders, and was fed by some CATV coax, buried in the ground. I lived in Rockland, MA. and could always hear Eastern Connecticut and a lot of New Hampshire and Maine on Low Band every day. On good days I could hear into New York and Pennsylvania, when everyone else couldn't hear the other end of the county.
Anyone know of any good plans for a homebrew scanner base antenna? I'm mostly interested in 100-200mhz and 400-500mhz.
I don't have a whole lot of space, so I'd rather not go with anything like a dipole.
Couple of links
Off-center has good comments, on my list to build.
Twinlead is for 2m Hand held replacement of the rubber ducky. So easy to make it worth a try. For your frequency of interest it might be useful.
how could a dipole take up space? I have two in my bedroom in my apartment. one made of aluminum tubing and a similar one with copper tubing. and another that is a Off Fed Center Dipole that is aluminum tubing used for portable base station setups. All three are homemade. I mounted mine on poles attached to camera tripods and the like. works well. the tubing is 1/2 inch and broadbanded for scanning use.
I was thinking about another unit I had seen that is a 2m/440, dualband jpole, the link was just a quick grab. Arrow antennas make a dual band jpole that could be easily built from scratch. Check here,for a pic a dual band jpole yes they do exist.A dual-band J pole?
A simple high band groundplane will work fine. It's almost all I ever used for scanning in that frequency range until I switched to discones. J poles are ok for single band operation, but just ok. I never much cared for them.
High band is usually 150-170mHz, as opposed to low band, 30-50mHz, but then some consider 800mHz to be uhf high band, you decide.When you say "high band", what frequency should it be designed for? Are discones typically the best for scanner antennas? Is it possible to home brew one?
