D4VHF VHF and Microwave Station Antenna Systems Upgrade

The D4VHF team on Cape Verde Islands have recently made some major changes to their antenna systems for 2-metres, 23cms and 12 cms.

For 144 MHz, they have now installed three crossed 5-element Yagis stacked in a vertical configuration. These will be using Right Hand Circular Polarization and it is hoped that they will be able to make more contacts as the signals will be less prone to fading.

For the 23cms and 13cms microwave bands, they have installed a 1-metre homemade dish. They will be adding an elevation motor so that it can be used for moonbounce on 1296 MHz and 2300 MHz.

They also have an 80cm dish for accessing the QO100 satellite in geostationary orbit (2.4 GHz up, 100 GHz down).
