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
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
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
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
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
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
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
Here is a high-performance hand-held beam antenna that is easy to build and guaranteed to improve your downlink from the LEO satellites over ANY rubber duck or mobile whip. Like many satellite operators, I own an Arrow Antenna. That antenna is a great performer, but sometimes it is impractical for me to use it–it is
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
