The basic antenna is a vertical monopole, using elevated radials to complete the “ground plane.” I use it only on the weekends, primarily for contests, thus it is designed to be raised and lowered with a minimum of fuss. It is a full-size 40 meter 1/4 wavelength vertical, with from four to eight tuned radials…

A Stealthy 75 meter Antenna
The 75 meter dipole at K7ZB was put up to meet the need for making contacts with friends in the Southwest and Southern California. As usual, it had to be put up so no one can see it from the surrounding neighborhood. The objective was accomplished as shown below, which is the site drawing for…
20/40 Dual Band Dipole
This is a simple dipole built for two-band operation that I made for portable use with my 20 and 40 meter QRP rigs. It was built to take along camping so I would only have to take & put up one antenna instead of two. The antenna consists of a regular 40 meter dipole using a…
2 element Yagi for 10 meters band
A 2 element beam antenna for 10 meters band Living in a condo has many advantages, none of which is being able to mount a tribander on a 60-foot tower. So I make do with a long, thin random wire that works nicely as long as the New England wind, snow and ice don’t conspire…
DL2HCB Multiband Delta Loop
After a Qth change last year, I was fortunate to get permission for an outside antenna. The new antenna was built with the following considerations in mind. At least 10 – 20m coverage Open wire feed to simplify matching the various impedances Loop design, because it is less sensitive to nearby objects and it requires…
A Practical Antenna for 160 Metres
Original article published by G3YCC “This aerial is one I have used for top band (160 metres) – it was suggested to me by Alan G4ERZ, also of Hull. It consists of 140 feet of insulated wire, the first half of which (70 feet) is space wound on an insulated tube. I used glass fibre…
80M Vertical Antenna with Capacitance Hat
Design Criteria: Simple wire antenna; Cheap to make, using readily available materials; Low angle radiation, with rejection of high angle signals; Wide bandwidth, with resonance at the 80M DX window (3.790-3.800 MHz); and Maximum height is 40 feet (limitation due to treeheight). Design: Since the use of a full ¼-wave vertical was out of the…
A multi-band super mini loop antenna
Here’s how to make the “Super” antenna. To build this antenna you need a lot that is at least 100 feet across.(This can be on a diagonal). Antenna covers all bands 80-10 meters + 30, 17, 12 meter WARC Bands This antenna works as a Full Wave Loop on 80 Meters and also works as…
A 160 meter antenna for small lot
My back fence is 50 ft from the rear of the house and not enough room on the property for 80 meter wire antenna must less a 160 meter one, and this to work great with the sloper wire attached to a fence, I also use monofilament (non-conductive) line like fishing or Weed Eater line…
A short dipole for 80 meters
The antenna above has been described by Nadisha, 4S7NR and may be of interest to anyone wishing to get on 80M (3.5MHz) that have limited space available. L1 is 12 feet. L2 also is 12 feet and the overall length is 48 feet. The two loading coils are described as 67.83uH and can consist of…
