There is no other band that is affected by so many forms of propagation as 6 meters (50 MHz). Sporadic-E (Es) in summer and midwinter. TEP (transequatorial propagation) around March/April and September/October. F2 propagation and aurora in periods of high solar activity. Meteorscatter and the almost daily present troposcatter. But Continue reading The Hula Hoop Halo; a simple DIY antenna for 6 meter band DX→

The Cobwebb is an antenna that has gained in popularity in recent years. The horizontally polarized omnidirectional antenna is suitable for the 10m, 12m, 15m, 17m and 20m band. All elements are fed through one single feed line. At only half wave length above the ground, it will outperform any Continue reading A different approach to tuning the Cobwebb antenna→

Better horizontally than vertically polarized If you only have limited space for an antenna, but still want to DX on HF on multiple bands, you will soon have to rely on a vertical antenna. DX’ers among us know that on the 10 and 20 meter band you can often work Continue reading How to build a limited space 10 and 20 meter band Square Halo DX antenna→

In most cases, radio amateurs love it when their antenna resonates, because a resonating antenna is usually an efficiently radiating antenna. At least, when we talk about electrical resonance and not acoustic resonance. The latter can cause considerable nuisance and even dangerous situations. Fortunately, there is an effective and inexpensive way to keep Continue reading Is your antenna making noise? Use a rope!→

Quite a long time ago since I posted on my blog. People around me know I had quite some issues past years with my wife’s health. She had a stroke in 2016 and things changed for our family. I had throttled down my job and quit as board member of Continue reading Upgrading the vertical for the lower HF bands→

I have a license to operate all HF bands, but my Hustler 4BTV 4-band trap vertical only covered 40m, 20m, 15m and 10m. Now the 80 m band is the only band which allows me to work NVIS night and day across the region here, while 1 m is a Continue reading CG-3000 remote auto tuner on HF vertical review→
