Thanks to "crookedninja5" for this simple, useful antenna "tuner" for the 2-meter amateur/ham band.
"Crookedninja5" says the idea for this project came from a desire to make his homebrew coat hanger VHF antenna more broadband.
Here are some of the steps used by this radio amateur to make this homebrew antenna "tuner":
"I needed something to make my clothes hanger antenna a little more broad-banded in the 100-200 MHz range, so I made a simple antenna tuner from junk... this would work for scanners too....
The variable capacitor can be any 0-365 pf capacitor... for c1 and c2 a ceramic or trimmer capacitor can be used... c3 and the coil is all you really need... About 8 or more turns on the inductor coil with taps spaced out every other turn. The rotary switch is from a old indoor antenna... everything in this vid was from a junk box, except for the RadioShack enclosure.
Once you get the right combination of coil inductance and capacitance you'll see a difference it makes to your signal reception.
This setup can also be used for SWL in the 3-30 MHz range with a 1" diameter coil of 120 turns and a random wire antenna! The bigger your coil the lower you can go!"

The G5RV and its popular variant, the ZS6BKW, are popular multiband HF antennas for radio amateurs. In this video, members of the Stamford Amateur Radio Association W1EE, show us how to build a ZS6BKW antenna capable of covering the 80 to 6 meter amateur radio bands. Here are the guidelines offered by this construction team: "The ZS6BKW is the successor to the G5RV. It's a multi-band 80-6 meter wire dipole. ZS6BKW started with the G5RV and then conducted extensive computer modeling to increase the gain, flatten the SWR a bit, and smooth out the lobes. It's also about 10 feet shorter than an equivalent G5RV. The antenna must be fed with 39 feet of 450 ohm ladder line and also must have at least 70 feet of coax feeding the ladder line. The coax and ladder line together form a matching network that brings the SWR below 2:1 (

Don't let deed-restricted properties (HOA/CC&R) stop you from enjoying Amateur Radio. In this video from AC2RJ, we see how some well-placed trees, a camera tripod, a telescoping fiberglass mast, and a "V" antenna can get you on the air without a lot of effort. Add an antenna "tuner", a sturdy rig, such as the Yaesu FT-817, a microphone/cw key, and a simple grounding system, and you have a fully functional, nearly invisible ham station in your backyard.

Bernie does an excellent job of explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV). Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use. The G5RV is an excellent choice for the 20 meter band. Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.
