    It's the "honeycomb" type grill that's the problem @hammerdown.
    Look up "destructive interference"
    Basically The signals are getting to the detector unevenly which causes the detector to interfere with itself.
    I have tested multiple "professional installs" that placed the antenna behind the honeycomb grill. Needless to say all of those installers received an earful the next day lol.
    Literally it will decrease the antennas performance by at least half.
    Saying that i have my rear Net Radar antenna placed behind my rear non-metallic painted bumper and it performs flawless.
    The honeycomb is an absolute range killer.

    Good luck. FWIW, I've been dropping the GPS antenna under the dash (high up, say over the steering column away from metal and electronics) and it works well. Other than that, it's pretty straight forward. Also, I was able to slip the head just between the honeycomb on my z06, so I have a clear view of the road...relatively tight with some 3M tape top and bottom.

    Ive already got the gps (TX head) and i ran the cable up the passenger side A pillar and tucked the gps in between headliner and roof. Only signal lost warnings i get are when its sitting in the garage. Gets fine signal otherwise.

    Yeah, got honeycomb in lower grille, i can probably modify it a bit, recess the rd a few inches back with a clear view.

    Id like to go drivers side lower grille, just below black bumper. I want to keep V1 /JBV1 combo... V1 is high and tight above RVM on passenger side, so that should provide a good separation to minimize interference.

    Do you plan on cutting the grill to mount the antenna in front of the honeycomb?

    I do now.... :mmmhmm:
    [doublepost=1520804058,1520803604][/doublepost]Actually, i was thinking cutting honeycomb out in front of antenna to provide clear view and recessing antenna back a few inches.
    [doublepost=1520804297][/doublepost]Anyone got the dimensions of the dsp antenna?

    I'd consider what appears to be a plenty large slot immediately below the Ford emblem...

    I could do that as long as you think would be okay to recess it back 5 or 6 in. Reason being is there's a vertical plastic support built into the grille right there behind that Center
    spot. Id have to mount behind it. I would go to the side of it though so it would not be in the way of the antenna

    Can you build something to extend it out so it's more flush with the front?

    Possibly is it that big of a deal if it's recessed back though? I mean if it has a clear view....

    Why not go off center in a slot up there?

    Because I thought about going lower in the grill to help hide it. No my state doesn't ban radar detectors.... but they have banned laser jammers and I went to some trouble to hide the heads with actuators...

    .... it would be all for naught if Leo mistook that antenna for an alp sensor... or him seeing it and that making him to look closer at the front end making him discover the other items. In other words I need to hide something that's legal in order to make sure I hide something that might not be ;)

    Stealth. That's what this is all about. if I cant recess it 5 to 6in back then I need to put it flush down lower so it's hidden.

    I see. I think going pretty far back would probably create some interference. May be behind a flat part of the bumper would be your best bet for stealth and low interference. Good luck!

    Why not Actuator the NR too !! Or is it too heavy for your actuator install.

    Too heavy? Probably not. Too long? Probably. Remember rx heads are only 1 inch deep. Leaves plenty of room behind it for actuators and what not.

    I only want a dsp to run 2 tight sweeps. 34.600- 34.770 and 35.450 - 35.600.

    To pick up where my V1 may lag on 35.5 and sweep more 34.7....

    As I do have Moto Leo's around here with stalker 2 handhelds and those things are really fast. It has came to my attention that they could potentially beat my V1 with fast i/o from those handhelds, even though I run a pretty tight sweep set on my v1 for 34.7 when im in thier area.

    A second dedicated Rd for just those two segments would be nice. I'm just trying to decide if it's worth the price to do that and all the trouble to install since it sounds like I can't do it like I initially thought I could.

    Yeah it sounds like you're going to have to make some compromises to obtain that IDEAL CM protection you're needing.

    Good Luck with that my friend ...
    Trust me ... get your backup installed or you'll be sawry.

    You have ONE OTHER option

    Cut the hole somewhere BUT find a thin non attenuated plastic to cover the hole from BEHIND the grill or bumper.

    Cuts attenuation to minimum and stealths and hides the Antennae.

    If the cut is clean then wont invoke a second glance probably not even s first glance. !!
