    Default A couple of questions...in general.

    In the town I live in and the surrounding ones it seems Ka band is only being used. I just bought a RD recently so I haven't taken it too far or into any big cities. K band seems to be used for the door sensors and what not although I have ran into one X-band that goes off near a hospital.

    One of my questions is can state troopers be moving and shoot you with their radar if they are using Ka band? Is there a gun that does this, or do they have to be stationary?

    Another question is since im only using the RD locally at the moment and Laser doesn't appear to be used, wouldn't I benefit from the RD being mounted up high instead of low? There are lots of hills in the area I live and the troopers travel it a lot. I think even a second more reaction time would be a benefit. Also I want to mount it up high so it will be concealed behind the rear view, so I don't have to pull it down in case an officer is behind me and sees it. Obviously I would run the wire along the trim and not straight down. Although it is not illegal to have an RD in my state, I'd rather keep it hidden anyways.

    And finally, would I benefit from turning off the bands that are not used in my area? Would it speed up the RDs detecting time any?

    -Thanks

    X, K and KA can be used in motion. Laser can not be used in motion. If you mount high, you may get about a second or 2 better detection then one mounted low. Last, if you turn off bands, this will not speed up the detection any.

    Yeah, what he said...

Last, if you turn off bands, this will not speed up the detection any. However, if POP is enabled on your deetctor, people claim that it will be more sensitive to KA band. Not sure if that part is true though...

    What I was trying to say is if you turn off the bands you don't need, will it speed up the processing time of the unit itself any since it doesn't have as many to search for or whatever.

    It's not likely to do anything for you. X and K are extremely narrow bands when compared to Ka. I've heard of some European users improving performance by specifying only specific parts of Ka to scan, but that only works where your only concern is one specific device (probably a speed camera.) In the US you need to scan the whole thing.

    Incidentally, what kind of detector are you using? There have been discussions of the "best settings" for various models.

    Not necessarily. It all depends on the internal circuitry and what the sweep rate is (in milli-secs or micro-secs) for your RD to complete a cycle.

    However, I would not recommend (and many will agree) disabling any band all together for obvious reasons.

    Brick, I read about the "best" settings for my RX65 and have it set that way at the moment.
    SETITOFF, If it only takes less than a second to sweep then I might as well leave them all on. Didn't know how fast it processed.

    On another note, I mounted the RD behind the mirror so those behind me wouldn't see it. Looked good. Performed bad. I didn't realize it but the "arm" that mounts the mirror to the windshield blocked the antenna's range on one side so it didn't pick up much of any signals on that side. It actually skipped over a K-band signal that I always get when passing a grocery store. I'll see what happens when I mount above the mirror if possible and if not, right below it I guess. If nothing else it will go back down above the wipers.

    I wouldn't think so.

    Besides, what with karma being what it is, the minute you turn off one band, you'll get pulled over by a cop using it.

    Also, as someone pointed out, it only takes a second to sweep, so that's not any length of time that's going to cause you any detriment.

    However...I was of the understanding that radar detectors had to be mounted high to work efficently. I've got my RX-65 mounted right by my rear view mirror, and my boyfriend has his V1 in the same place (can you guess who mounted them both? ) I think that mounting them lower can affect their performance - you might find better reaction time by simply mounting it higher, rather then turning off bands.

    The general agreement is that the difference in radar range is very small. If you have a car that is treated with veil or is naturally hard to target with laser, you'd want to go for a low mounting. If you are an easy pick for laser, your best chance is to mount high and hope to get some scatter from other cars being lasered in front of you. Look at the "laser defense" section on the valentine site.
