Hello. I have a custom build by Innovatenna in UK. This is a Yagi covering the entire VHF aircraft band.
It’s never been installed.
We have a very wideband OP-DES design Yagi which we designed and produced
for Ofcom in fact. It covers from around 116Mhz to 136Mhz. This as standard
has a rear mount for vertical working with total length of around 2.2m.
