Kato that is spot on. Police radar is mostly circular polarized, with the exception of the Stalker ATR in the U.S. which is vertically polarized. Multanovas are horizontally polarized.

Do a search for "vertical +multanova" (check "Search for all terms" button) on the rd.net forum to get posts such as:
http://www.radardetector.net/viewtopic.php?t=24690
http://www.radardetector.net/viewtopic.php?t=25883
http://www.radardetector.net/viewtop...r=asc&start=15 - fourth post down

Also here are some videos:

http://www.delonixradar.com.au/videos/STi_vertical.wmv
etc etc

Simple test; do what Kato did, when you next find a Multanova, pull over in front of it and slowly move closer until you first get an alert on your detector. Then tilt the detector 90 degrees and watch the increase.

No worries, sure i can bang up something myself.
more so asking whether mine is built the same as the others and vertical mount will be an improvement.

Actually the 990i has Ka-narrow band, so you don't need it so much. Just make sure you turn on Ka-narrow 34.3 and the rest of Ka-band off. It will pick up Multanovas better than the RX65 or X50

Jez, whats the best detector for multinova over here in terms of distance picked up? $?

990i because of the narrowband. You can set it to look at just multinova frequencies rather than scanning the entire spectrum.

The best detectors against Multanova 6f is any, as saturation says above, that can be programmed to only scan narrow segments of the 2.6GHz Ka-band range (1GHz in Australia).

Think of it like a car radio. If you started at the very bottom of the FM band range, its about 88FM and the top is something like 106FM. Let's say you wanted to pick up an intermittent radio station at 96.1FM

If your radio had to always scan from 88FM up to 106FM when the only station you could possible pick up was 96.1FM then you see the wasted time in scanning the whole FM band (think Ka-band) for that one signal.

Now lets say you had a radio that you could program to only scan from 95.9 to 96.3 FM. Obviously it would detect a 96.1FM signal a LOT faster than one that was scanning the entire (super wide band) range.

Keeping with the analogy, Australia has a FM radio allowance of 88FM up to 106FM (without going out to my car to check exact). But lets say USA has an FM allocation of 82FM to 115FM. And if we bought a car radio from the USA and the only intermittent radio station we could detect was 96.1FM, and by design the radio had to scan the entire band, you can see why detectors made for the USA do not perform so well against Multanovas.

Hope you can follow along with the radio station analogy

So if we can program our detector to only scan small slices of the Ka-band range, we dramatically improve the sensitivity on low powered, weak signals like the Multanova.

**Side note... I just had a massive Deju vue**

Radars that can be programmed to Ka-narrow band scan are:
Bel 975 remote
Bel 966 remote
Bel 990I
Euro (Bel) Target 330
Euro (Bel) Target 550
Stinger DSI
Valentine One

The Bel RX65 and RX75 remote cannot.
I've even looked into the possibility of developing a software upgrade for the RX65 (seems so many have been sold here). We can download the software off the Eprom and flashing it isn't hard, but decoding the encryption and then reprogramming it with what we want and re-encoding it before flashing it back on is the difficult (costly) part. With all detectors they have sold at the "Australian Price" you would think Neltronics would invest in this for its customers.....but that's another thread.

So Stinga, for WA nothing comes close to a Valentine One. It kicks butt compared to the others.

There is also a new remote detector coming out from Bel which like the STi, is stealth (invisible to police radar detector detectors) called the Bel STi-R but it has an estimated retail of $1400 - $2000. Due August.

Radar detector detectors (RDDs) are used over east where Radar detectors are illegal. Since RDs are legal to use here, RDDs are not needed by the coppers in WA. So we don't really need to pay for extra $ for a stealth (RDD invisible) detector in WA.

The new STi remote does have Ka narrow, and the older Bel 975remote has it too. Unfortunately the RX75 doesn't.
