Hi?ÿ
So I have the parani sd 1000 hooked up to my topcon .They work great the issue is mounting the unit to the tripod at the instrument.?ÿ ?ÿ The cord only allows the antenna to be pointed downward like a gps rover.?ÿ
Does anyone have an idea to mount it to be vertically up ??ÿ Or will it work ok pointed down ??ÿ So far, I can reach out 500 feet?ÿ ?ÿ
?ÿ
Thank you. And happy weekend?ÿ

I cut an old tripod cover down so it was just a clip and tab, then hooked the parani on with double sided tape, pointing down, and it gets out about 800 feet.
I??m looking into getting this setup for my TS. Do your paranis??s have the longer antennas? From what I can tell they come stock with short antennas, with the option to buy longer antennas? ?ÿHow long do the batteries last??ÿ
Sorry for more questions. Maybe I should start a new post?
I have a small Seco pouch that has a small opening at the bottom for the cord to pass while retaining the Parani. It has one side with a clear panel and two velcro straps to attach to a leg on the tripod and the wire bail also on the tripod (Dutch Hill). I can't find a part # tag on it but it came from the guys at US Survey Supply in OR. Been real happy with it. Lasts all day with the extended battery. Line of sight range about 800' using the 5db antenna (6"). I'd send you pic but I can't figure the photo posting on this site...

My understanding is that BT uses a vertically-polarized signal, so as long as the antenna is more-or-less vertical it doesn't matter if it's pointing up or pointing down, as long as line of sight is unobstructed.?ÿ The farther off vertical you go the more signal loss, though I routinely have the antenna on my data collector at a zenith angle of maybe 60 degrees (it nestles against the prism pole at that angle and is thus better protected against mechanical damage) and have no trouble connecting out to 1000 feet or so.?ÿ Higher up in the air is better simply because that tends to improve line of sight, but the difference between pointing up and pointing down for a given mounting probably isn't significant.
I left a model of the Parani in the 3D models if you have any interest in designing your own widget, this was my widget.?ÿ I second Jim in that the antenna needs to be vertical, but, polarity doesn't matter
polarity doesn't matter
My understanding of polarity as it concerns antennas is that it refers to the orientation of the propagated wave with respect to the earth's surface.?ÿ A vertically-polarized wave is perpendicular to the surface, while a horizontally-polarized wave is parallel with it.?ÿ It's an orientation thing, not a positive-negative thing.
The set of Parani came with a seco bag.?ÿ I'll use the bag at the like as shown in the picture above .I guess since the cable at the instrument is so short, I'll just clip it to a tripod strap bracket and let it point down.?ÿ During practice, I was able to get 500' easy.?ÿ ?ÿ
I know the instrument tracks the prism much better with BT than it did with the original infrared RC 2 unit .?ÿ ?ÿ ?ÿI don't know how long the battery lasts or how quickly it will charge.?ÿ ?ÿI'll check out Norms post?ÿ
Thanks?ÿ

Polarity of the field, we are saying the same thing
