This is post 2568 in a continuing series of simple ham radio antennas.

An antenna transmatch (i.e. tuner or coupler) is a familiar piece of equipment in many ham shacks.  "Tuners" insure that impedances between antennas and transceivers are matched to allow maximum efficiency.

In this video, Michael Martens (KB9VBR) shows us how to properly use an antenna "tuner" to maximize your antenna system.  Michael uses the popular MFJ-949E (I use the same tuner) to demonstrate basic "tuner" concepts.

Here are some of Michaels comments:

Antenna tuners are a vital, yet slightly misunderstood ham radio station accessory. In this video we talk about what an antenna tuner does and doesn't do, how it works, and how to tune your antenna system with a manual antenna tuner.

Amateur radio transceivers expect a 50 ohm impedance from the antenna, but not all antennas will deliver that impedance. That’s where the tuner comes in. A tuner typically consists of an inductor and variable capacitors can be adjusted to create the proper impedance. Now tuners don’t actually ‘tune’ your antenna. They don’t change the physical characteristics or make the antenna better. Instead they just provide the proper impedance match to the transceiver, so the transceiver can operate in a more efficient manner. #AntennaTuner​ #HamRadioHowTo​ #HFradio

G5RV Multi Band HF Dipole Antenna. Post #1555.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=aeNHIQ_j4Dk This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH).  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.

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.

Here's a way to use Amatuer/Ham Radio while you work on shedding a few pounds in useful exercise.  Why not equip your bicycle for 2 meter/70 cm mobile operation? In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station.  The project is straight forward, simple, and gives you emergency communications while you peddle down the road.
