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
The Handi-Tenna 70 cm Portable Antenna
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
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
2 meter Cubical Quad Antenna
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
An easy dual band VHF UHF Antenna
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.
