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

Building a ZS6BKW antenna from scratch. Post #1559.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=BfUbL_4VCww. 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 (

Antenna for Condo Backyard-Stealth. Post #1542.

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.

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.
