fun with scanners #4 Build a simple VHF / UHF antenna matcher
This is a little project that i have been thinking about building for awhile now, this is a VHF and UHF antenna tuner / matcher. This item well help you tune a random rubber duckie, outside antenna, or just a whip so your scanner well be able to RX better then it could before, depending on the coil used and just as many taps on it, you can fine tune a antenna perfectly to your scanner radio. I built this tuner and tested it on the bench with my Uniden Bearcat BC-796D 25-1300mhz scanning reciever.
Thoughts and Modifications of mine on the Vectronics VC-300M 300 Watt Mobile antenna tuner.

Of course, it goes without saying that this isnt the best method to do mobile HF without permanently securing the radio. The radio is being held in place by rubber grip pad. However, since I do much traveling in rental vehicles, this is the risk I take to enjoy mobile HF. But am mindful of the laws of inertia if I slam the breaks! Thank you Mr. Newton.
