Thank you, Mike B !

Would you mind my cross-posting your information to the RD.net thread, if you haven't made that contribution, there, already?

As this was in response to a question on this forum, It is not my call as to how or where this information is to be used.

To make this a new thread on another forum based solely upon my response is possibly undermining this forum.

I do not recall the rules of this forum but you may wish to read them in their entirity before cross-posting to any other forums.

I would not want you do do anything to go against the rules set forth in this forum.

X band: 2.5–3.75 cm
Ku band:1.67–2.5 cm
K band: 1.11–1.67 cm
Ka band: 0.75–1.11 cm

If I have this correct, would such a mount theoretically decrease the reception (potentially) of X and Ku since the actual wavelength is longer than such a vertical separation, given the potential angles (venetian-blind effect) versus straight-line radar?

Thanks Mike for your input on this matter.

Certainly the lower frequencies would be most effected based upon your statement however if it is possible to mount in a location other than the chrome plated plastic grill, I would choose the alternate location for the following reasons.

First and formost would be my confidence to receive radar from as wide a field of view as possible.

Placing behind your chrome plated plastic grill may lower the preformance on X and Ku from directly in front of you, but my concern for K and Ka would be if radar was not directly in front of you.

There is a venetian blind effect as well as the openings are smaller when looked at from an angle making the potential of reflecting K and Ka and thus reducing the cross sectional area that your radar horn was designed to receive.

At some angle the venetian blind effect will be completely closed severly hampering your sensitivity.

As a side note, if you are not concerned with off axis sensitivity, there is one possible benefit to mounting behind your specific chrome plated plastic grill in that you may be less sensitive to X band door openers as well as possibly some K band door openers that are set back from the road as long as your vehicle does not point in their general direction.

Indeed, that was where I was going with this one.

(X and to a less-extent K) stuff way off to the side, I don't particularly care about. Stuff way down the road, of course, is a different matter entirely.

Given that both remotes are installed and by and large their relative performance is generally very very close (in two discreetly different mounting locations), I am expecting that my particular mounting locations are pretty decent.

My Bimmer's front fascia may limit ultimate placement and I couple that with the concern that openly exposing (to the road elements) a sensitive piece of electronics (despite its housing) gives me a moment of pause.

Perhaps, I will play around with alternate locations now that I've got nearly a year under my belt with both units...who knows, I may actually be able to enhance performance even more. I'll definitely leave that possibility open...

At any rate, I really appreciate your commentary on this subject, Mike.

I'm an academic scientist, myself - biological.

I'm along mindset of the more information is freely shared, the better.

It is not my intent to open a new thread on RD.net, based solely on your response above, but rather, to add to the thread already there, as-with what was done, at Veil Guy's request, a few posts before.

I make it a point to always read such, before actively posting in any on-line community/Forum. I've been on-line since there was an on-line (as a part of academic science, participating in the early days of what was then to be the Internet, as well as for recreation, via BBSs), and yes, this has always been my own personal rule, that I ask, before I re-post or cross-post, and that I also, in a most rudimentary and non-formal way, cite sources, to both give credit where credit is due, as well as to insure that the information shared is accurate, per the original poster/writer.

The only rule I remember, from the community "Mission Statements" ( MISSION STATEMENT: Forum Rules and Posting Etiquette ) that applies here is, I think:

^ And I thank you, for making sure that I stay in the good graces of our host, as well as the general community here!

And finally, as this reply comes late, for both you and Veil Guy, would you mind my prompting the guys over at RD.net to give these latest responses a read, and also post the last two replies above, from the both of you, respectively, to the appropriate ongoing RD.net thread on the 9500ci RADAR mounting concerns?

The discussion above is tremendously informative, and I think will be of-benefit to the entire community.
