RD Antenna Patterns

[TruckingIT]

I have a somewhat technical question requarding an RD's antenna pattern.
Does anyone know of any published antenna patterns for Escort's detectors?
Of course this is a antenna design question and may not be publically avaliable.

Here's an example of TV antenna reception patterns. Scroll the whole page to get an idea of what I'm asking.

More sensitivity in the front than the back or about the same.

Thanks,

The center lobe on the X axis in the rightmost graph in the following photo from that web site probably pretty closely matches the horizontal off-axis reception pattern of the M4 horns used in many of the Bel and Escort RD models.

That's the answer I was looking for MEM-TEK!
Yea, the right pattern was about what I had in my mind.
I suppose that Escort's actual patterns is a trade secret or hasn't been published yet.


Thanks for the info!

Note that the pattern will vary with radar band and will vary somewhat for the 33.8, 34.7 and 35.5 frequencies on Ka band. But more or less the shown pattern should be fairly close.
