Important: Head Positions on your ALP Install.

[BestRadarDetectors]

When installing a dual system you do not want to place the heads too far apart from each other (For example under each headlight) that is too far apart for sensors in a dual install. If you do a Triple install and have one under each headlight but also place one head dead center that configuration will work fine. Just realize its important that heads be installed in order when doing a Triple front install. (F1, F2 & F3) and the F2 head needs to be in the center position. Its best to also post photo's of your install and we will mark out suggestions for optimal placement. You can post your photo's in the ADVICE ON PLACEMENT thread. Its also a good idea to preview others installs before you install your own.

are the rules for buble location still the same for ALPs as they were for LIs?

Heads are small.. Moving the Bubbles only moves the receive or transmit less than 1" either way. That small difference really will not make any difference.

thanks thats what I thought.

they are small and thats why I asked it seamed that with LIs there was so much talk about bubles in/out but you don't hear it anymore.

What is the optimal spacing for ALP? In inches or cm.

What is the optimal spacing for ALP? In inches or cm.

and what have you found to be the threshold for what's "too far away" and what's "sufficiently close" enough to work with just two heads?

I know the rule of thumb used to be 18", but the ALP's are more sensitive and it looks like we can get away with farther spacing.

Every car is different and its best to post a photo and have us make some recommendations. As a rule I would not space them over 24" apart from each other.

Its funny, BUT that's about the recommendation for the ALF CS56 IIs as well........................(AKA the Rental Car Temps)................

I'm a bit confused in terms of sensor coverage as the Youtube video here appears to show one sensor unit, mounted vertically in the grill of a BMW X5 and one on the rear providing full coverage against various lasers. What do folks think of this?

My understanding is that a single head is enough for some guns... Probably when it comes to the variable pulse rate guns, you need two heads.

I cannot remember the reason behind recommendations against vertical mounting.
