Curious Antenna Array

Not my photo but I was asked by the photographer if I knew what it was - I don’t! It is a line of 16 vertical antennas at Pointe de Brezellec, Cléden-Cap-Sizun in Brittany, France. This is near Brest which is a big naval base so might be part of a trial/experiment. I am guessing they are VHF antenna, possibly marine band, and might be for range/direction finding.

But other suggestions welcome. :slight_smile:


It looks like a big phased array of short verticals, for receiving on HF. I imagine each one will have an identical broadband amplifier at the elevated feedpoint, carefully selected feeder lengths all connected to a complex phasing network to make it steerable.

Gavin, thank you, I hadn’t thought of HF. It isn’t a permanent installation I think, so must be some sort of trial.

Just been sent another image. My contact found four more antenna set in a square.

The long red line are the 16 antenna in the original post. The red square is the four new ones. The circle is where he is parked!

As normal Google has the answer!

Its the linear equidistant array of 16 receive antenna for a HF radar, centred on 12.4Mhz. It studies the ocean surface. There will be a transmitter site in the same area.

Rather than active receive antennas, they are probably just 12.4Mhz verticals with elevated radials.

Looks like a sea surface radar setup.

EDIT: Sorry was talking to Mrs. FMF and when I hit post there was Gavin’s answer :blush:
