220 MHz Antenna Scan


This is a cheap 220MHz Ham band 1/4 wave magnet mount antenna I built. I didn't have an antenna for this band so I could use one.

The bandwidth of 1/4 wave antennas can be surprisingly wide at VHF and more so at UHF frequencies. They are also very easy to make, just trimming the antenna to get the SWR down as close to 1:1 at the center frequency of the operating band.

When I'm out at swaps if I see a magnet mount in good condition real cheap I'll buy it. I also picked up a bunch of 19 inch stainless steel whips with a 3/8-24 stud mount. These I cut down for a particular frequency that requires an element less than the starting length of the whip.
