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’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
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
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
Double Bazooka Coaxial Dipole Antenna Info There is a lot of controversy surrounding the Double Bazooka Coaxial Dipole. Its bandwidth claims have sometimes been exaggerated. On this page I give details of how to build two different versions of the Double Bazooka Antenna. One antenna uses all coax the other uses coax and twin lead
by AG4DG The Issues A full-size antenna for HF (except for the 10m band) is not feasible for apartments due to the space required. An apartment antenna should have the following characteristics:
