Got my first callsign on 1979 as EB2DN after a couple of years in CB band with home made equipments. Later on got the

callsign EA2ATZ which did not used much due to lack of ($) equipments. In 1982 family moved to Benidorm and then I changed

my callsign to EA5DOM. I have been out of the hobby from 1995 to 2010 busy into rising a family and a job

Now my main interest in radio are new technologies, weak signal techniques and the microwave bands


Antennas are located in top of a 90m building tower in Benidorm. Currently the antennas are:

HF: 7MHz to 50MHz Ultrabeam dynamically adjusted lenght vertical antenna. The antenna is working as vertical dipole

using one 1/4 wave cable radial for each band hanging down from terrace. This setup works much better than radials

horizontally distributed. I use this antenna for WSPR and OPERA  most of the time for RX on 476KHz and 136KHz with very good results

Yagis are installed into a 1.5m tower section with AZ rotor and two telescopic mast poles with the following antennas:

50Mhz LFA Yagi 4 elements

70MHz LFA Yagi 4 elements

DK7ZB 144/432 Yagi 4+5el in vertical pol. using Elevation rotor for sat

DK7ZB 144/432 Yagi 5+8el in horizontal pol. using Elevation rotor for sat and tropo

Tonna 35el for 1296MHz using elevation rotor

The box attached to the elevation rotor holds the 1296 transverter and 50W PA, and relay to switch V/UHF polarization

With this small setup I have been able to work some Big Gun EME stations in 1296MHz

I'm NOT using LNA in Rx because the transverter has good enought gain and low noise and the trick is

to have just 1,2m of cable between transverter and antenna. All the rest down to the QTH is the IF at 144MHz

Worked so far five initials

PI9CAM 31/5/2014

UA3PTW 7/9/2014

K2UYH  24/12/2014

I1NDP 6/1/2015

There are some other stations which I can copy at my limit but they can not receive me with only 50w and linear



In order to deal with the high winds and sleep better I decided to make the Yagi installation fully collapsible

So it can easily be folded down flat on ground. To make this possible I had to modify the attachment of 50 and 70MHz

Yagis with hinges used for aluminium doors
