Simple Ham Radio Antennas

One of my favorite HF antennas is the classic delta loop.  You can feed the antenna with 50 ohm coaxial cable for single band use or connect the antenna to an antenna transmatch (i.e. "tuner") with balanced feeders for multiband HF operation. In this video, Hiram Vazquez does an excellent job of explaining the theory, design, construction, and use of the delta loop antenna.  The delta loop has some gain, receives well, takes up little space, and is fairly cheap to make.  You can mount the delta loop horizontally, vertically, or in a sloper configuration.

In this well-made video tutorial, Hiram Vazquez takes us step by step through the design, construction, and use of a Delta Loop HF Antenna.  As Hiram explains, delta loop antennas are fairly quiet on receive, show a bit of gain over a dipole antenna (about 3dB), take up little space, and are cheap to build.  Delta Loops can be both mono band and multiband, depending on how you feed the antenna.  If you use balanced feed line (300 ohm tv twin lead, 450 ohm ladder line, or home made 600 ohm balanced line) with a balanced "tuner", multiband use is possible. If you can use only one HF antenna on your property, the delta loop may be what you're looking for.

It has some gain, receives well, exhibits low noise, takes up little space, and is fairly inexpensive.  In this video, Hiram Vazquez discusses the theory, design, construction, and use of this versatile, easily-made antenna.  You can use balanced feeders in conjunction with a 4:1 balun and an antenna "tuner" to attain multi-band capability.

Here's a simple antenna that you may want to try for your next Amateur Radio activity. In this video, Hiram Vazquez takes us step-by-step in the design, building, and use of a Delta Loop Antenna.  The Delta Loop receives well, exhibits low noise, shows some gain over a dipole antenna (about 3 dB), and can be built from locally available materials.  You can feed a delta loop antenna with 50-ohm coaxial cable for single band use or with 450 ohm ladder line for multiband use. For multiband coverage, design the antenna for the lowest frequency of use, use 450 ohm ladder line as a feeder, and run the feeder through a balanced antenna "tuner" or a 4:1 balun before connecting the antenna system to your HF transceiver.

My favorite amateur radio antenna is the easily-made and efficient delta loop antenna. In this video from Hiram Vazquez (WV2H), we learn the basic theory, construction, and performance parameters of this versatile HF antenna. Delta Loops display modest gain, have low noise, take up little room, and are inexpensive to build.  At my QTH, I have a delta loop similar to Hiram's.  The antenna's total length is 142-feet/43.29 meters and is attached to the top of a 33-ft/10.06 meters telescoping fiberglass pole.  The bottom portion of the delta loop is supported by two 10-ft/10.06 meters bamboo poles. The antenna is fed by a length of 450 ohm ladder line running into a 4:1 current balun. A short length of RG-8X coaxial cable connects the balun to my trusty Drake MN-4 antenna transmatch.  A small piece of RG-8X coax connects t...

The Delta Loop is one of my favorite antennas.  It's simple, easy to build, and inexpensive. Plus, the delta loop can give you a modest amount of gain (about 3 dB).  Multi-band use is possible if you use ladder line, television twin lead. or homebrewed balanced feed line connected to a 4:1 balun and fed into your antenna transmatch (i.e. "tuner") with a short length of 50 ohm coaxial cable. This video from Hiram Vazquez covers most of the steps needed to make this highly versatile HF antenna.

Exceptionally well-done video from Hiram Vasquez on how to build a Delta Loop Antenna for 20 meters. Hiram uses a simple Q-Match to make the antenna resonant at approximately 50 ohms--perfect for any 50-ohm coaxial cable you may have around the shack.  Most of the materials can be bought at the nearest hardware store or home improvement center.  The object in back of Hiram is the rope he uses to raise and lower the 20 meter Delta Loop.  The antenna is simple, elegant, and easy to build.  If you want coverage between 20 and 10 meters, replace the 50-ohm coax feedline with 300 ohm television twin lead or 450 ohm ladder line in conjunction with a 4:1 balun and a short length of 50 ohm coaxial cable, which plugs into your antenna transmatch (i.e. "tuner").  This Delta Loop is bi-directional and exhibits some gain.  For the lates...

A clean, simple tutorial by Hiram Varquez on how to build a delta loop antenna and a Q-Match for it. According to Varquez, "The Q-Match will make the antenna resonant at 50 ohms at the feedpoint. This eliminates the need for an expensive balun." The delta loop antenna is bidirectional and exhibits some gain over a dipole. The loop is compact, easy to build, and inexpensive. Although Hiram's delta loop is designed for 20 meters, you can scale the loop for any amateur band between 160 and 10 meters, depending on the space available. If you want to use the delta loop for HF bands above 20 meters (12, 15, 17, and 10 meters), replace the coaxial cable and Q-Matching Section with 450 ohm ladder line and a balanced tuner. Delta Loops are excellent antennas for home or portable use. For the latest Amateur Radio news and events, please check out the blog sidebars. These news feeds are updated daily.
