Tri-Band 2M/220/440 mobile antenna
Keep in mind the SBB-224 and SBB-224NMO are a 1/4 wave on the 2M band. A 1/4 wave is only half an antenna, the other half is the ground plane underneath it. Installing a 1/4 wave on 10 different vehicles will create 10 different SWR results. The SWR on a single band antenna can be adjusted by adjusting the length of the antenna to compensate for the difference in impedance provided at each mounting location. Not so with dualband or triband antennas, the power feeding coil is pre-set at the factory.
If the SWR is elevated, adjust the antenna location until you find the the best SWR.

When I received my call sign a few years back, I was flooded with purchases of junk. Fast forward to 2019. I decided I wanted to build another option, not a dealer who has the same stuff as everyone else, but a dealer who actually uses what he sells. And that’s exactly what I do. If you see a product on this page or one of our tables at Hamfest, you can bet we have tried it and like it. From Radios to connectors we strive to bring you QUALITY. Sure, you can find it cheaper and we understand that, but if you don’t want to buy it again in 6 months, take a look at what we sell and have already approved. I am always just a phone call away. Jim Gifford, KM4MPF.
