If you need a simple, quiet antenna that covers the 15/12/10 meter amateur radio bands, please consider this horizontal loop from Sandy (G4XRV).  The antenna is fed with balanced line and, apparently, doesn't need an antenna transmatch (tuner).  This design can be scaled for any range of amateur radio bands, if you build the antenna for the lowest selected frequency and use an antenna transmatch to reach higher bands.  I have a 40 meter delta loop which covers all ham bands between 40 and 10 meters.  I use an antenna "tuner" and 450 ohm ladder line to keep the rig happy.  If you can only use one antenna for HF, consider building a delta loop.  You won't be disappointed.

Barbed Wire Antenna. Post #1659.

If you can't view the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=j_itg93_Fes. Just about anything can be used as an HF antenna, provided you can match the impedances between rig and wire and have a suitable ground radial system.  In this video, WA5PMO uses a random length of barbed wire fence for his antenna.  Apparently, the emergency lashup works, saying "I worked Canada on 20 meters from Wixon Valley, Texas (using) a Yaesu-879D."  Be sure to tap your creativity if you need an HF antenna in a hurry.

If you can't view the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=Dw1rz0CVn90. Here's another exceptional video tutorial from Julian (OH8STN).  This video demonstrates two different antennas, both built on the popular Chameleon magnetic Loop Starter Kit.  Either one of these compact antennas will prove useful for those living in deed-restricted homes (HOAs and CC&Rs) or for those needing a small, effective HF antenna for field or portable use.

Vertical Dipole in Tree. Post #1657.

If you can't view video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=RI2_T-LeYEU. If you have a tall tree on your property, you may want to try this antenna.  As Stan Gibilisco (W1GV) explains, this multiband HF antenna can be used where space is at a premium.  Each leg of the dipole should be at least a 1/4 wavelength at your lowest frequency of use.  An antenna transmatch (i.e. "tuner") and ladder line will permit multiband use.  Try this simple antenna and "work DX on a budget."

If you couldn't attend Pacificon 2018, you missed one of the true highlights of the Amateur/Ham Radio event calendar. Thanks to Randy Hall (K7AGE), we have a recording of one of the most inspiring and passionate defenders of the Amateur Radio Service speaking before an overflow crowd at this prestigious meeting of radio amateurs.  Jeri Ellesworth (AI6TH) shows a love and in-depth understanding of what Amateur/Ham Radio means to our communities and to ourselves.  A masterful stroke of optimism for an age of cynicism and doubt.

Using a wire fence as an HF antenna. Post #1655.

Image
If you can't view the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=IRh11KM2w8A. Almost any metal object can be used to receive HF signals--in this case, we find a wire fence pressed into service as a random length wire RECEIVING antenna.  The operating position consists of a Yaesu FT-817 and a MFJ 16010 L-match "tuner".  Transmitting with this antenna could present some safety and equipment problems, although this operator didn't mention any difficulties in getting the fence to work.  Antenna experimentation can be a learning experience if safety procedures are followed.

Installing a Mobile Radio in Your Car. Post #1654.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=FzBDf-JEa3w. Installing a mobile radio in your vehicle can be easy if you follow the steps outlined by Pete Hadley (K6BFA) in this video.  Pete shows how he installed his 2 m/70 cm transceiver and antenna in his vehicle without drilling large holes in the vehicle body and by keeping all wires and cables out of sight.  A very efficient and operator- friendly installation.
