My antennas system

HF antennas:

In the end of October, 2009 I finished another antenna experiment, I designed and build 30 and 20m rotatable dipole. Later I plan to add to this antenna 40m band.



In the end of July, 2009 I finished work on the construction of a new DX'ing antenna. This is a completely new design, which evolved from my previous design of my antennas. It is 100% my design and execution. What really is the antenna? This antenna is something between asymmetric vertical dipole and the GP antenna with only one radial. At this time, the antenna works very well in the bands 80/20/15m, minimum SWR = 1.2 at each of the bands. I planned expansion this design for next 40/10m bands.



In a short time with only about 50-100 Watts I made some new DXCC, which confirms the effectiveness of this antenna. Later I will present full design with full details of this antenna, let me finished this.

List of new DXCC made on this antenna: YB-YH Indonesia, S2 Bangladesh, PP-PY Brazil, LO-LW Argentina, K,W,N, AA-AK United States of America, J2 Djibouti, JA-JS Japan, JT-JV Mongolia, JY Jordan, 3B8 Mauritius, 3DA Swaziland, 5N-5O Nigeria, 5T Mauretania, 7T-7Y Algeria.

In the past, more than three years for all HF bands I used wire antenna G5RV. Since the summer 2006 I used a new version of this antenna called "Better G5RV". This antenna was connected to my rigs via ICOM Automatic Antenna Tuner model AT-130E.AT-130E. I no longer use this antenna.


In the 6m band I use two antennas:
  • wire single delta loop
  • homemade two 3-elements yagi antennas based on the DK7ZB project


VHF/UHF antenass:

2m band (FM mode) is operated by simple homemade J-Pool antenna, it works fine for local QSOs till max 30km. I use it for listening satellite and ISS too. In the midlle of October 2007 I decided to buy and install duobander GP antenna for 2m/70cm, Diamond model X300.


VHF/UFH satellite and DX operation antennas

Antennas for amateur satellite and DX operations are just building and testing, I plan to use two cross-yagi, antennas for 2m and 70cm. In the pictures below you may see two yagis antennsa based on the DK7ZB projects.

The first one is 7ele Yagi antenna for 70cm band based on the 1m boom.
Gain at 432 MHz =10,5Dbd
3dB angle horizontal = 42,8 st
3dB angle vertical = 49,4 st
The feed point is 28 ohm at 433 Mhz



The second one is 5ele Yagi antenna for 2m band based on the 2m boom.
Gain at 145 MHz = 9.0 dBd
F/B > 20 dB
The feed point is 28 ohm at 145 Mhz


All yagi antennas will be managed by Azimuth & Elevation rotor.

HF 14m GP antenna for DX-ing for lower bands.

In the middle of 2008 I made decision to build and test HF GP antenna for the lower bands. My first GP antenna consists of three sections of ALU pipe (6m + 4m + 4m), connected each others, total it was 12m. Unfortunately, few months later during autumn storm wind the antenna was broken. My QTH is a small village located about 20km away from the coastline of the Baltic Sea and is situated at a height of 173m above sea level. The quite strong wind here is almost the year.

The second version of this antenna was built in the beginning of 2009 with the 6m ALU pipe (55mm) + 8m fiberglass pole. From the mechanical point of view this antenna exercises without guy-ropes are pretty good. Thus, this summer, I plan thorough to rebuilding this antenna for the DX-ing purpose for.
