VHF Antennae
3B8FO has successfully built and tested the following two vhf antennae .They are easy & quick built antennae which can be made from available "matierre de bord" materials.
The plans for the building of these can be downloaded from the following links.
VHF pocket antenna
This one is built directly and fixed using electrical insulating tape at the top end of a vertically erected fishing pole some 15 flt long .
Normally with his 1/4 monopole he cannot access DM at Le hochet with his 5W radioditty HT ,but with this one he can easily access his station with a very good signal report.
BAN at B.Du Tombeau also gave him a very favourable report compared to the monopole.
4 element vhf yagi
The antenna is some 20 ft on a manually rotable pole.
Direct line of sight with BAN did not give any result.However,to his surprise beaming the antenna towards DU got him a satisfactory report from BAN and of course a very good one from DU.The BAN reception is most probably due to reflection from a 10 storey building some 300 ft from 3b8FO's antenna.
3B8FO intends to do direct line of sight tests with St Denis in the coming days after doing link budget calculations using a software whose downloadable link has been kindly given to him by DU.
Please let us know in case you have built anyone of these and any changes /improvements you have made.
BAN is experimenting on J-Pole antennae and is having encouraging results.
