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…
This antenna does not need a 75 Ohm transformer as quads do at lower frequencies. Any length of a good quality RG58X will suffice as the primary feedline. Connect to station with any length of good 50 ohm coax and PL-259 connectors and one barrel connector to couple the feed lines. This antenna can be…
This article taken from QST September 1994 is about a vertical dual-band antenna for 144 and 430 MHz made with a TV twin lead and coax cable.
Editors notes: The antennas described in this article were built as the result of several discussions between Kent and a Cuban radio operator. While there are plenty of high performance antenna designs, most of the parts required to build them are not available in Cuba. There just isn’t an EPO or Radio Shack available in Cuba….
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…
