9500ci and STi Radar Antenna Horns

Think it might just be firmware? To answer your question: yes, I'd spring for an STi-R and mount it high and inside if it had modular wiring (and improved audio ramp-up). I'd also be ecstatic with an STi non-remote if I could get that kind of sensitivity out of it. I just upped my warranty in hopes that they'll offer such an upgrade.

UP.

I had 9500ci antenna inverted (sticker to the ground) for few weeks.

It's interesting because sensitivity was noticable better when front of the antenna module was plainly up (about 7-8 degrees) than leveled (0 degrees).

But now my antenna is mounted correctly (sticker up, almost 0 degrees, maybe 2-3 degrees up - it's placed really low, about 15 cm from the ground) and seems to work better. I mean max distances of detection maybe are equal but when mounted correctly they are more stable and this is noticable very clearly for Ka band.

Example for extremely low powered and angled 34.00 GHz source and normal traffic conditions:
- antenna inverted: 362m; 202m; 134m
- antenna correct: 354m; 284m; 314m
