Bad Sensitivity?

[polecats03]

I just got my V1 last week from the factory and the rear antenna seems to be a lot more sensitive. I get amazing range from the rear antenna that goes for miles, around corners, around buildings, etc. The front one seems to only detect like .25 miles ahead if that... I had a RedLine and it was simply amazing but too much $$. Just wondering what might be wrong...

I ran into that same exact issue for a while, and actually posted a thread about it on this forum. For me, it was my mounting location. When I was having these issues, I had the V1 mounted below my tint strip and to the left of my rear view mirror, if I'm not mistaken. I started expirementing with my mounting locations a little more, and to make a long story short, I eventually mounted it as high as I could behind my tint strip. After mounting it there, the difference was like night and day. I started getting very, very good range after that little move.

Why my detection sucked below the tint strip, I don't know. Something in the windshield was affecting it. I'd mess around with different mounting locations, if I were you. If it still seems to be acting weird, you may want to give Valentine a shout.

Yeah I am at a loss... it has a perfect view of the road... Its mounted up high and a pretty clear view of the road... I had my redline there also and it was amazing. If I have to send it in for a tune up when it is a week old I will tell them to refund me and Ill go back to the redline.

Try mounting it low for a few days. I'd even mount on the back window. You could see the arrows from the RVM.

Interesting... I notice better range with the rear antenna on mine.

I'll move it a little lower. You may want to give that a shot as well.

I Agree w/ya that's a sweet spot for a RD to be mounted, and I also would be concerned if another RD was performing well from that same spot. Hopefully you didn't get a bad service job back from V1, that would be highly unlikely but not impossible.

Damn rear antenna, you would swear it got better range if it was not for tests, I even think mine gets better range (but unless V1 messed up in the factory, its all in my head).

Its the big finger print in front of the lens on the glass, lol. I would mount to the left of the RVM.

A few points about the rear antenna:

- The rear antenna is about as sensitive as the front.
- LEO's coming from behind will alert longer than the front.

This is probably in the top 5 complaints amongst V1 users......but be SURE you really have a problem before sending it back.

The front antenna is larger and should easily be the more sensitive of the two but the rear antenna is going to pick up signals that the front will miss.

The wider antenna in the front is actually more narrowly focused giving it more straight ahead range and less off axis sensitivity. The narrow antenna in the back will have better off axis sensitivity but less reach compared to the front.

Find a stationary signal and back out the fringe detection range with the front antenna pointing at the source. Then simply turn the detector around and see if you can pick it up with the rear antenna. If your pointing right at the source and the rear antenna outperforms the front THEN you have a problem.

I know kband door openers aren't a great test but I drive past the same one everyday and with redline it alerted so quickly. V1 I drive by then the rear arrow lights up. Redline seemed to go off before I even came close to the sensow. Guess ill try mounting it just above and to the left of my rvm. I like where it is now though. Almost touches roof n from behind it looks as if.its part of my car.
