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!
In a previous post I did a review on the X-phase QRM eliminator. I found out that the antenna for receiving QRM, the auxiliary or secondary antenna, holds the key to optimum performance of the QRM eliminator. A single wire along a shelf in your shack is, for what I Continue reading Boost your QRM eliminator performance with an active antenna
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
I love HF and my QTH is not that good for harbouring a lot of antennas so I can work each band. I do have a trap HF vertical but it is a pain in the … Corrosion makes this antenna untunable to resonate.The ideal antenna would be a vertical Continue reading The liquid HF vertical for 10m to 40m
Lucky me!!! No better way to test the homemade 10m Moxon antenna then with current conditions. Best propagation since 2003, definitely! I took the chance to do one on one tests, and results are a bit surprising in a positive way. But first of all for the right comparison: Moxon Continue reading Nice propagation to test the Moxon antenna
I made a setup with a dipole and the 10m Moxon antenna to compare results. But for some reasons both antennas acted not normally. The Moxon had almost none front to back ratio and the dipole could not be tuned to resonate with a decent SWR. It seemed that the Continue reading Let’s start testing the 10m Moxon antenna, or not…
Since a few weeks the 10m Moxon is up and running. It was quite an easy job assembling and mounting it. I have constructed it in a way that makes it very easy to assemble and disassemble it in case of a severe storm (which happens here frequently). From a Continue reading Moxon up and running, first impressions
Well, I got all the materials for the new 2 element Moxon, a more ridged than the previous one that was blown of the roof… This time I am using 20mm PVC tubes as spreaders. I have attached the spreaders to a mast made out of an old piece of Continue reading Working on the homemade 10m Moxon
