I was in need of an antenna for my 10 meter beacon, so I decided to build a design I remembered seeing in an issue of QST several years ago. A friend of mine built one at the time and it worked great. It is a simple rigid dipole made from two lengths of 1/2″…
YagiMax
Even if outdated, is still a good program to calculate and desing yagi antennas elements dimensions, sizing and spacing. I’ve used it to verify some antenna plans I’ve found on the net. It’s particularity is that you at first need to tell the program the size of your antenna and then, you can calculate resonating…
The flower pot antenna
About the project It’s a portable dual-band antenna working principally on 10 meters but also close to the 30 meter band. It’s compact, light, economical and doesn’t need any radial.If you would like to repeat my experiment you will first need a big plastic flower pot (around 70cm high, 60 top diameter and 30 cm…
How antenna traps work
Article by VE3GK I was assembling a HY/GAIN, TH6DXX, a 10 – 15 and 20 meter beam the other day and thought there might be some interest in the function of the traps. I have also included some practical information on howto build traps for a multi-band, 10-15-20 meter antenna. RESONATE PARALLEL NETWORKS REVIEWED: When…
K9FD Receiving Loop
RECEIVING ANTENNAS The K9FD Receiving Loop The Answer To Suburban DXing On the Low Bands – by K9FD Editor’s note: Merv Schweigert, K9FD, has been working jusl about everything on the 40, 80 and 160 meter band” this season. In this article he shares some of his experiences with receiving antennas. lf you live on…
Make a magnetic loop antenna for 7-21 MHz
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…
