Hello forum. Does anyone have operating / factory manuals for the?ÿ Yellow/Grey TopCon LegAnt base Antenna? Used typically with the Legacy E Base receiver. It looks like the Javad Green LegAnt might have been the original Mfg and TopCon purchased the design. I'll take the Javad LegAnt manual if anyone has those as well. TopCon Tech Support did not have anything in their system I talked to dealer support today. Thanks, TK

Update;?ÿ
Javad emailed back today, they said they don't have any manuals for LegAnt. So anything would be great.?ÿ
I have an old unit sitting in the closet, what do you want to know??ÿ The Legant antenna was made by topcon, after the partnership with Javad - the old company, not the current one.?ÿ There are green versions of that as well, I may have one of those around too.?ÿ It is just an antenna, and can be paired with several topcon & javad receivers - of which I still have lying around also.?ÿ I really should clean the closet out.
As it is just an antenna, aside from wanting to know where to measure to (the bottom mound vertical, and the rubber on the side for slant) not much too them.

The only critical thing about pairing is that the receiver sends power to a preamp in the antenna assembly, and you need to make sure the voltage is compatible. My Trimble antenna has a sticker warning against using it with the wrong receivers.
Thank you Bill, right now we are using the green Javad LegAnt with no issues; however I??d like to use the Yellow TopCon LegAnt - the voltage inputs of 5V are the same .
Main question is; are these antennas fully interchangeable, ie do they share the same dimensional offsets, that??s what I was trying to validate with a OM manual. I plan on field testing the yellow LegAnt and comparing redundant shots both horizontally and vertically but was trying to see if I need to create a new antenna config in my controller first , hoping data sheet would tell. ?ÿThere is NGS antcal data for the green one (JPS Legant E:)

but I could not find one on the topcon LegAnt to compare. Any thoughts on your experience would be appreciated . Thanks!?ÿ
@toivo1037?ÿthanks for the reply , i accidentally typed the reply for you in Bill??s reply box by error. Getting used to this forum format, thanks!?ÿ
I took a quick look and don't see any manuals for the legant antenna -sorry.
My green and yellow copies are slightly different physically.?ÿ I know the green and yellow hipers are interchangable, and the legacy receivers are too, but these 2 antennas are a bit different in construction.

When I searched my computer for legant, I got this from an antinfo.txt file:

@toivo1037 Hi Tovio, If you are digging around closets, I'd like to possibly buy one of your green Javad Legants so i have a backup unit on my shelf. The second one I have is questionable. send me a PM and we can take this offline and not clutter up the thread and bore guys to death. TK
