Several different brands of radars were used. That's because many of the radars were purchased by the county officials and county governments (locally). In my restoration, I chose to go with the tan counter box and tan colored antenna heads from Decatur. For my car, that wasn't exact but it works and few if any know the difference or even remember.
But there were SOME '93 Texas cars that had my kind of Decatur (tan colored) radar and I have pictures to verify.
A lot of the Texas cars had the BEE Stalker units. But finding one not working (for me) was difficult so I went with the path of least resistance.
Some of you probably prefer the radar to be operational. Mine is inoperable and not hooked-up. It's for cosmetic only anyway.
