This antenna has several advantages, not least being only 1 metre diameter! This loop relies on being horizontally polarised and receives only the magnetic wave, thus as most noise in the domestic environment is vertically polarised and electrical wave, it delivers low noise to your transeiver/receiver, which makes for nice clean listening. In addition any…

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…
The Copper Cactus Antenna
Dear Fellow Hams Here are the numbers for the Copper Cactus J-Pole antenna!I hope you are already familiar with the construction of the standard J-Pole antenna, so I won’t go into any unnecessary detail. The antenna may be built as a MonoBander, DuoBander, TriBander, QuadBander or whatever with great success.You can either feed it with…
The SIMPLE 2m/440 Copper pipe “J”
Can you use a pipe cutter or a hack saw, can you solder – then here is how to build a SIMPLE ”J” antenna that will more than double your 2 meter (and even 440) performance! by Dale “Kuby” Kubichek, N6JSX
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…
2 Meter mobile antenna
Do you have trouble getting your mobile signal into the LEO satellites? Try this small 2 meter vertical antenna with your mobile rig or HT and enjoy more success in your uplink. I built this small vertical because I could not uplink very well at low elevations and I just could not bring myself to…
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…
