Car Alarms: Shock sensor and microwave sensitivity, stage shock sensor, microwave sensors

Question
I have a Scytek dual stage shock sensor and a Scytek dual stage microwave sensor. The microwave sensor has almost no range. Is this normal for most microwave sensors? Basicly it has enough range to protect my CD head unit and that's it. Big let down on that component. The shock sensor is not very sensitive. After trying 4 different locations I can tap the fender or the hood and get it to warn. The sensor is oblivious to the rest of the car. Someone could easily break my rear window and jack my amp with this current setup. Both sensors are maxed on sensitivity. I'm going to order up some DEI sensors and see if they are any better. Thought about trying some Omega ones also. I'll be adding them to my current sensors. Greg at Scytek said he'd adjust the microwave. Seems like it should come with more than a couple foot range. Is this normal for most sensors? How many do you need for really good coverage? At 12volt.com they are pretty clueless about what sensors can and can't do. Don't think they really worry about it. Odd since they are the most important part of the alarm.

Thanks!

Answer
Did you diode isolate the sensors from each other?
If you straight tap the microwave to the shock sensor
without a 1 amp diode, you may (in your case do)
loose quite a bit of range on both.
I suggest one or the other, rather then do
both as it seems that yours
is not going to function as planned.

Greg's a good guy, he at least will try to sort
out the trouble with the end user. Try using
just the Microwave sensor and set it at about
9 oclock as you look at the front of it.

Let me know it it helps. If not, there are certainly
other sensors you can try.

Good luck.
