80 Meters 2 Element Quad Antenna
Introduction A rotating quad for 80 meters are you crazy? well i did it and it worked well. now i’m not saying that i think anyone else be as nuts as me but it seemed to fun be idea at the time. i remember calling into a local 80 meter net on 3.755 mhz asking
HF Receiving loop antenna
Receiving HF signals at my location is a compromise situation due to the antennas I use and the high noise environment in the city. Although my transceiver has good selectivity and excellent filters, I suffer from high noise conditions that at times make receiving a chore. This is true for both weak-signal DX as well
4 Elelemt Yagi Beam Antenna for 20 meter
On picture 1 you can see the GK 4 element 20m yagi on a 40ft boom on the construction pedestal for the 20m stacks All of the yagis were built on the pedestal you see under the beams. Omega match on this new yagi for the 4X4 stacks has been adjusted using a TS-50 and
End Fed antenna
This end fed type of antenna was marketted in the UK and is a useful system for the portable set-up. Being a half wave, no radials or counterpose wires are needed. As the impedance will be high at the end of the wire, some form of matching unit is needed and a simple parallel tuned
The RockLoop Antenna
W9SCH described this small loop in Sprat 60 and it has proved useful to the QRPer, especially where space is at a premium. It is basically a variant of the usual magnetic loop, using a toroid balun to get a reasonable match on the three bands. A slow motion drive would prove useful on the
CobWebb 5 band antenna
I have a very small back garden and am limited with what type of antenna I can use. I built my first antenna in July 2004. If you are looking at this after speaking to me, you know it works. It is basically a 5 band antenna comprising of 5 full half wave dipoles for
The ever-popular inverted L antenna
Ever wanted to install a shortwave receiving antenna FAST?!!! Then I am almost sure that you will want to learn more about the “Inverted L” antenna… About the easiest effective skywire to build … Just two supports… may be two masts, a mast and a tree, a mast and a nearby building… it need not
A Novice Multiband Vertical Antenna
Putting your first ham radio station together can be an expensive proposition. One way to cut costs is to keep the antenna simple. Here’s how WB1FSB shaved the price and provided four band operation. https://drive.google.com/file/d/1os8GDj9Ydcp93W6r9TxBPJXp7zqPJOGu/preview
Homebrew G5RV All Bander
The G5RV is an easy-to-build 80-10 dipole requiring no traps. All bands are covered, including 30, 17, and 12. The G5RV has high SWR, by design, on most bands and a tuner is required. Unlike most dipoles, the “basic” design is not a 1/2 wave, but instead a 3/2 wave dipole on 20 meters. A
