OLD Antenna - now is down

 

16 Elements (4.4wl) DJ9BV for 144MHz.

40m above the ground, 150m asl.

Full elevation using an 18” TV actuator.

The Antenna control system is basically intended for the EME activity, with moon tracking algorithm embedded.

 

NEW Antenna System - is on the way

 

2x14 Elements (3.6wl) DJ9BV for 144MHz.

 

Rotator

 

PST2051 antenna rotator from PRO.SIS.TEL, GS-065 thrust bearing from YAESU.

 

 

 

 

 

 

 

 

 

Power splitter

 

From WiMo, combines two antennas by coaxial power splitters.

 

 

 

Preamplifier

 

CAV144EME preamplifier from LNA Technology

 

Transceiver  

 

TS870 from Kenwood, modified to work with my homemade transverter.

 

 

 

 

 

 

 

 

 

144 to 28 transverter

 

BF988 transistor in the first RX stage, SBL1 mixer.

7W output from a BLX68 transistor.
