Yes, two wire grids spaced a half wave apart and clocked at 45 degrees from each other. Cute trick.

Didn't you have a Rotapol? I remember seeing another WISP's install and they had a reflector dish and a Stinger on the Canopy SM. I thought "those idiots!" Haha. I was the idiot.

Very high index of refraction but had some loss issues. It would focus on a spot, now if that spot had a single mostly square patch antenna like the original canopy, they you are golden. But if not then it would not work as well. I don't recall what the 430 and 450 had for antennas. I do know it could be used as a murder weapon and had about 7.5 dB when used with a regular SM. So it was never a competitive threat to the stinger. I don't have too much memory of the CLIP. ________________________________ From: AF <[email protected]> on behalf of Adam Moffett <[email protected]> Sent: Tuesday, November 3, 2026 1:02 PM To: 'AnimalFarm Microwave Users Group' <[email protected]> Subject: Re: [AFMUG] memory test - did Cambium LENS work with 450 SM? I thought the lens worked on all of them. I thought that was its selling point. ________________________________ From: AF <[email protected]> on behalf of Ken Hohhof <[email protected]> Sent: Monday, November 2, 2026 11:03 AM To: 'AnimalFarm Microwave Users Group' <[email protected]> Subject: [AFMUG] memory test - did Cambium LENS work with 450 SM? I think I discovered a 450 SM at a customer site still with a LENS. I thought we got rid of all of those (they made nice doorstops and paperweights). Does anyone remember if you could use a LENS with a 450 SM? I thought it only worked with 430 SMs, although I’m not sure why it would care single or dual pol. I thought with 450 you had to use a CLIP or Stinger. Or am I remembering wrong, maybe confusing it with Chuck’s “focus ring”?
