Great descriptive information for those of us that aren't on your level...thank you. Very cool thought from the Radenso team! And a good precursor to what we can expect. The anticipation continues.Ok...…..speaking of prototypes...…..this showed up as part of my contest awards!

I would definitely not mind if THIS were the production horn inside Theia...…….completely CNC machined from a solid block of aluminum!

This is some real artwork and a beautiful assembly! I incredulously asked Jon if this was a production horn (can you imagine the time to machine this) and not surprisingly the answer was no. Production horns will be cast from magnesium and have some fins added to double as a heat sink. None the less it will be based on this design........just different materials and fabrication process. Would there be a noticeable difference in performance? I don't know but the lines on a cast horn will never be this crisp and sharp while flat surfaces may be a bit smoother. Also you have what may amount to different electrical properties between the two metals. So I don't know if it would be a straight up apples to apples comparison between this prototype horn and the production model (but I certainly wouldn't mind having this one under the hood).
Now for the dimensions of the horn itself. This very much reminds me of Escort's compact S7 horn...….a fabulously balanced horn with a relatively mild and consistent taper and small aperture. Less directional than larger horns like that found inside the Uniden LRD950. This should give it tremendous off axis performance while leaving the RF circuitry to extract as much straight line distance as possible. Wider antennas with a more pronounced taper would make the antenna more directional or give it a bit more gain to signals in perfect alignment but start dropping off and losing gain the more out of alignment you get with the source. For RDs I prefer a balanced horns like this and the S7 / M3 / V1G2 with excellent off-axis reception.
Here is a comparison between Theia and the horn assembly out of the Uniden (which is similar to the current Radenso models)

Last but not least is the labyrinth inside of RF isolation chambers and microstrip tunnels. A very elaborate arrangement that provides a separate stall for every element on the strip line filters! That's pretty crazy!
I'd like to thank Jon for sending me the ball cap and sticker...….but to see this in the bottom of the box blew me out of the water! It's like getting a moon rock from Nasa.
Dimensions: 5 1/4" Long and 2 13/16 at the widest point (mounting bosses). Horn dimesions: 1 1/16 W x 9/16 H x 1 3/4 long. Comparatively the Uniden is 1 9/16 W x 5/8 H x 1 5/8 long.
I so need one of those for my Corolla.
