False Ka

**quandary** · 11-13-2006, 10:18 PM

Last week, I started getting Ka false from my driveway (strength 1). I haven't been able to vector into the location. Anyone know of any garage door openners or alarms that cause Ka falses? I live in a subdivision that has no commercial properties close enough.

Any satellite dishes? My ExpressVu set off my Sensoro without fail. The STI won't though.

Some ultra modern high end motion sensors will cause your RD to alert to Ka. At my office we have one.

I hope they are not mass spread like K band, or a RD will officially become useless on the highway.

satellite dishes X2!

My neighbor has his Direct TV satellite dish mounted about 2 feet off of the ground...it gives me a weak Ka reading everytime.

With my STi, i get a little Ka band every now and then from my garage door. But if it helps, next door have a big sat' dish hanging over our drive way as well :?

^^I get the same thing with my STi. I reset, and it goes away, or it really is the Satellite dish next door... Not sure why. It is random and a reset seems to fix it.

Does it go away and not come back? A hard reset may make the detector go into that POST that takes about 15 seconds before alerting to something in the area.

I drove around and now know which house is generating the false Ka. I will speak with the owner soon.

Satellite?! I beleive they are only receivers and not transmitters (hence the big dish). When I had 3 dishes set up against my garage, I never received any falses from the dish. I have also worked with satellite systems that transmit up to the satellite but there are too expensive and I doubt any home would have it. (It does not false either.)

Motion sensor. Possible but the cheaper home ones are usually infrared. I suspect this is more probable.

You said you know which house it is, but what is it thats creating it?

Satellite TV is definately only one-way. However, the recievers are just like radar detectors, they mix in the signal and leak out harmonics like a mad sonofa*****.
