You may well be right in theory. But no BSB receivers had such a pot and no squarials had the electronics to change the phase. They had to be aligned just like a dish but because of their small size the acceptance angle was wide.

I've just found my BSB offest mini-dish, if anyone is looking for one. Haven't found the LNB yet. Should it have the little cone over the circular waveguide, like the one on Wikipedia? You can't see that very clearly, so here is mine just now.

I recall they could be used with some other sattellite (Thor?) at the time, but needed a modified receiver.
Does anybody know if there is any currently used sattellites using circular polarisation? Tony.
I had read many reports of the Squarial being circularly-polarised, but in my later experiments it seemed to be linearly-polarised. Pointing at a conventional H or V satellite transmission, it was possible to null out the signal by rotating the squarial by 90 degrees. To me, this indicates it was not circularly polarised.

Two more Squarials regularly spotted...

Squarial 1 in North West London. Can't get close enough to see if it was a BSB one and will never know now as it has been removed in the last few weeks.

Squarial 2 - Seen again on my bike ride today, a regular route.

Pictures from Google Streetview.

There were quite a few early Satellite viewers here, it is the same street where I remember delivering an Amstrad-Fidelity Sky system in the late 1980s as a Saturday boy at the Co-Op. Letchworth wasn't a big enough branch to stock such luxuries, these could only be sold through the larger Stevenage Branch. My boss wasn't happy about that and got a couple of systems in from the warehouse, but they wouldn't supply him with any advertising material. The Window Dresser made some cardboard dishes with hand-drawn Sky logos on, putting them in the window got the sales going.
