Hello forum members.

I have a new Hw4 HiFi ALP system that includes a GPS antenna. I am considering adding the Net Radar DSP system and integrate it with my newly installed ALP. I have two questions:

1 - Will a second radar antenna installed in the rear of the car provide me with just directional awareness or does it add additional protection?

2 - Do I need a second GPS antenna or will the integrated Net Radar system leverage my existing GPS antenna that is installed with my ALP system?

Thanks

1. If you want direction you need to connect both a front and rear antenna and that will enable direction.
2. There is only one GPS antenna and if you already have it on your ALP you do not need another.

the second antenna will add arrows and a little more sensitivity to the rear, the front antenna is pretty sensitive so even if you have a radar source behind you it will pick up signal from it (reflections and such from things ahead of you) so you will get some warning if there is a cop behind you with radar, just not as much range. I find with my Uniden R1 (which is very similar to the netradar performance wise) that I can get up to a couple miles of rear alert distance (some times it's only half a mile or so, depending on reflective objects around me what frequency etc) but it's generally sufficient. most windshield RD's only have forward facing horns... the arrows are nice for figuring out where the signal is coming from, but after some time you can generally figure it out without them. so it's up to you, if you want as much range to radar thats behind you as you have for radar thats ahead then add the rear antenna

A big thanks to BestRadarDetector and thebravo for addressing my questions. I appreciate it.

I already have a windshield mounted RD but like the idea of removing my RD from the windshield. I have just spent days, not just hours, installing my ALP. Yes I am a DIY. So I have just about run out of my free and available time. I will probably add the Net Radar net year. I disassemble my car, removed front bumper, rear bumper, seat, and carpeting, to accomplish a quality installation. If I knew then what I know now, I would have added the Net Radar at same time as my ALP.

Thanks again.

Yes I already have a GPS antenna plugged into my ALP control unit. Question:
A. Must the GPS antenna remain plugged into my ALP control unit
or
B. Unplug the GPS antenna from my ALP control unit and plug it into my ALP RG module

Thanks

Once you install an RG3 Module the GPS antenna needs to be connected to the GPS Port on the RG3 Module.

Why wait?
I used modified Max360C suction mounts for both front and rear NetRadarDSPs to get online asap and avoid issues with bumper placement, metallic paint, etc.. In a year of HOT summer days and cold winter nights, I have not had a single mount failure.

You can add the Netradar unit without removing the front end again. I removed the front of my 15z a half dozen times for various reasons but I installed the ALP and Netradar without removing it on my 19z.

That is good to know. Where did you install the front NetRadar antenna? A quick pic will be most appreciated.

Thanks

Sorry it took me so long. I didn't see your post. I used sugru to mount the heads. I made a jig to make sure the ALP heads were straight and level. I had the jig from the 15 I did but I couldn't find it this morning. I pulled the wires in beside the radiator on the passenger side. I didn't have to drill any holes. there's a hole on the passenger side at the front of the door that's covered by the black seal. All of the wires will fit through it. I put the control under the glove box and ran power from the power outlet on the console. If I can help just pm me.

Hello @Z062015

Very nice job on the installation, fantastic. And thanks for the additional tips. I observed in the pic that you have the NetRadar antenna in the center and a total of two ALP sensors. I also observe that the car includes the factory parking cameras. But, what is that thing on the passenger side at the top-end of the grill?

Thanks again.

I track the car more than I drive it on the street. ZL1 addons had the most unobtrusive tow hook I could find so I bought it and keep it in. I got black so it wouldn't be obvious. I have racetech seats and 6 point harnesses in the car. For some reason, camera angle I guess, the sensors don't look level but I went back and checked and they are. I had the Stir + antenna first and swapped it for the net radar. Then I bought a new control unit and put the Stir + and 2 alp front sensors on that. If I start getting laser alerts I'll buy a transmit sensor for the truck. The car is too low for it to work well.
