I have the Stir + installed in my vehicle and it still warns me long before I can see the radar emitting vehicle. I have had it for 4 years and I was wondering if it is still good enough? I use it alongside the ALP.
BTW I live in the SF Bay Area and travel down to LA for time to time.
Thanks,

The only downside to the STi-R+ is it has zero BSM filtering for K band. If you can turn off K band or if the K band falses somehow don't drive you nuts then its great.

I have set it up according to the RDF local guide. I do not get bothered.

Yeah, it's still very good for Ka band so you should be good-to-go in CA. I see some k band in NC so I run my StiR (segmented to Ka only) in combination with a Max 2. If I lived somewhere that only Ka was used, I'd be perfectly happy using the STiR by itself.

Since they don't really use k band in California you can run with that off and it will do fine. If you were in an area where k ba d was used you would probably find the Kband falses to be excessive. Paired with ALP it should be a solid setup for CA.

I was also looking at Stir + to use with the ALP but found they are no longer available. I have heard they are quite stealth to spectre.

Anyone have any experience with Stir + and Spectre III or IV/Elite?

They're basically undetectable unless you are literally inches away if even at that. Still awesome at Ka, K band with TSR On may be tolerable in rural areas.

I was just wondering if there is any difference between the Bel STi-R and Bel STi-R PLUS antenna?

I read that the Bel STi-R was upgraded to the Bel STi-R PLUS in 2010 but not sure of the differences?

The STi-R Plus added the GPS and laser shifter capabilities of the 9500CI. The radar antennas however are not compatible between the two systems and the original STi-R antenna is actually more sensitive due to Escort switching to a prepackaged LNA for Ka/K bands instead of the previously used wire bonded LNA.

Ok that's interesting. Do they both have the same stealth properties? And are both versions compatible with ALP blue tooth controller?

I have 2 STiR+ in the car and K band is horrible. Road trip to FL it was muted 70-80% of the timie because between trucks and cars it never stopped picking up BSM. City mode helped quiet it down a lot.

Where I live, BSM falses aren't so bad.

Like others said, Ka band is great. I picked up over 2 miles with it behind my nose cone.

You should be able to find another + antenna on eBay for cheapish. Here's one for $160


You'll need to find the older ALP module though.

That said, if you already have it installed, and you aren't having problems with it, just keep it. But if you switch cars, dump it.

Thanks I did see that one on ebay but where can I get the older ALP module from? There are also some 9500CIs, are they the same antenna?

I was going to buy these but you are saying the Sti-R wont work with these ALP units?

Ok thanks, that's interesting. Do the three antennas, STi-R, STi-R + and 9500CI have the same stealth properties and compatibility with ALP? I gather as long as the ALP is an older controller.

I don’t know about ALP compatibility but @BestRadarDetectors could probably answer that. I do know they are all stealth however.

AFAIK what changed in the latest control unit won't impact the radar addon module so the old one should work you just can't use RGV3 with STiR

You'll need:
- GPS
- Control unit
- STiR antenna
- RG V2 module.

The Sti-R & 9500CI Antennas are extremely poor with the worst K band Filtering. We stopped supporting these antennas years ago. If you can find a used RG2 module you can still connect one to an ALP but in my opinion its not worth the trouble.

He lives in the SF Bay Area so he only deals with Ka band

(edit: I think I got the users confused since both had D avatars)

Thanks for the confirmation and I agree for most purposes, particularly in the US, the DSP that you now support is great and is stealth enough for most purposes particularly with Spectre IV/Elite.

However, I'm not convinced that it has sufficient immunity to Spectre III in some circumstances. Whilst I don't think this an issue in most areas including the US or close to cities or busier areas, in rural outback Australia where we often get mobile HWP, probably some with Spectre III, and often with only a few cars on the road within many miles, any sniff from a Spectre III would make them come after you, given there are no other cars around or other possible sources for false positives.

This might be a rare occasion but I can see it potentially happening in our rural areas. Though I'd like to be proven otherwise with some good video evidence showing what conditions the Spectre III picks up the DSP.

Unfortunately, until then the Sti-R or 9500CI antenna with the ALP seems the safest option in my area.
