Rhombic for 6m One thing I have fancied playing with for a long time is the Rhombic antenna. It has a very good directional gain and in principal is easy to construct. The problem is that on HF a Rhombic is extremely large. Even on 6m the antenna is pretty big! My idea for the … Read more
The antenna consists of: 1:1 Balun Lengths of copper brake pipe approximately 1m long pipe and secured into grooves in a length of wood. “Stingers” which can be moved to adjust the length and secured with grub screws. It is secured to the mast with a stainless steel clamp.
Years ago I bought a commercial but cheap HB9CV antenna for 6m. I think in terms of dB per gram of beam aluminium, these antennas are top-notch and great for /P. (I have had a lot of success with good DX with my 2m version.) However, rushing a first activation (contest) a few weeks after … Read more

Back In “radio science”, ‘Q’ stands for Quality factor. In a simple resonant or tuned circuit, (and indeed also in a single inductor or capacitor), Q is conveniently summarised as “the component’s reactance divided by the component’s resistance”. The higher the Q, the lower the loss in the component’s resistance. (In most tuned circuits it … Read more
Hello everyone, I am sure, like me, you have been following the news and government reports surrounding the coronavirus.

Over … Read more
AB INITIO Back Puzzling facts As we approach the festive season of Christmas crackers, games and puzzles, it was thought once again that it would be appropriate to divert to something “Scientific” rather than strictly “Amateur Radio”.
