RX65 questions!

**mazda3_GT** · 07-30-2006, 01:30 AM

1. what's the average range that RX65 can detect a radar gun ahead in the city or on the highway?(mine can only detect a radar around maximum 1km to 2km ahead. It never detects a police radar 4.x mile ahead like Roy's test report)

2. Does the detection range decrease if the signal is coming from the back of the car? (my rx65's signal strength can only reach maximum 3 or 4 bars when police pass by me from rear end of my car.)

3. In what situation the signal strength can suddently pop up from zero to full bars? (K or Ka warnings)

4. Can I use a laser pointer to test the functionbility of laser detection?

Thanks for answering.

I am no expert but i can try to help with a few of your ?

1. It really depends normaly those test of like 4 miles are on empty flat roads this means ther is nothing to block the radar. When you are on the highway there are turns, trees, and other cars blocking the radar signal.

2. The rear detection is likely to be somewhat lower. You can try to increase it by giving your detector a clear view out of the rear window. If it is mounted low and a seat is in the way you will lose some sensitivity.

3. It sounds like instant-on radar. Here's the deal the gun is in standby and doesn't emit any signal until the LEO pulls the trigger (when he target you are a car near you). So what is going on is that you are driving and you suddenly get a full alert is that you just got shot by instant-on.

4. No, the only reason i know is because i have tried it.

The laser pointer wont work because laser pointers are around 650 nm and police laser is 904/905 nm.

The RX-65 only has a front-facing antenna. It will still alert to radar that it behind you, but this depends on the radar reflecting off of things in front of the vehicle (buildings, signs, terrain, etc) and into the front antenna. So encounters with rear radar will vary depending on the area and terrain.

V1 have rear antena too:

So even with a good radar detector, we are still vulnerable with instant on detection??

Yes, especially if you are the lone car on the road. That's why you want a sensitive RD, to pick up the radar when cars infront of you are being targeted.

Yes. If you are a lone vehicle on the road, you're basically a sitting duck. Unfortunately, a detector will protect you more on a road with some traffic on it than on a road with little traffic.

People on here might mention following "rabbits": pick another car that is speeding and wait for him to pass you, then stay 1/4 to 1/2 mile behind him. The idea is that if he's speeding, he'll be hit with radar first, and you'll get an alert on your detector telling you to slow down....
