A very small active antenna

Small active antennas like the “mini-whip” (by PA0RDT) are very popular at the moment. They provide good reception of signals from HF all the way down to the VLF band. Here in the Netherlands Van Dijken Elektronica sells a nice…

HB9CV-in-a-box antenna for 23cm

The HB9CV has been a popular antenna for decades, especially on the 2m band where it is commonly used for direction finding (foxhunt). Others create arrays of HB9CV antennas for DXing. Since I needed a simple antenna for 23cm (to…

J-pole antennas for HF bands

Introduction I’ve been using J-pole antennas on the 2m band from the first day I got licensed. They perform very well, are easy to construct and are cheap. Since Adrian PA0RDA and I have been experimenting with vertical antennas for…

Bad luck

Since Adrian PA0RDA was ill during the contest weekend, and we were not able to setup all antennas due to poor condition of the field, we decided to skip the PACC contest. However, on Sunday morning I could not resist…

Successful contest

20m vertical repaired

The replacement tube for the 20m vertical arrived. I immediately fixed the fibreglass pole and erected the antenna again. It’s working great again. I also moved the guys to the top of the third element (instead of the second element),…

We had some nice weather in the last weekend of October, so I went into the corn field to do some long walks: setting up the new beverages (length: 80m each) and the HEDZ. We bought some new, higher poles…
