Antenna part or model numbers

[Piffery1]

Gentlemen:
I recently purchased a 1995 Thor Chateau travel trailer. It had all the user manuals except for the Winegard antenna. The antenna picks up a few digital signals. It cranks up/down and rotates ok.
I want to add a Wingman to increase UHF gain. I cannot find a model or part number on either the batwing style antenna head itself or on the interior power supply panel. Where are the model numbers or parts numbers located?
How can I determine if the antenna is amplified at the head or at the interior panel or not at all? The interior panel has an antenna input, Set 1 and Set 2 outputs, a cicarette lighter type Receptacle, a power Switch (pushbutton) and an indicator Light.
Will the Wingman work satisfactorily with any version? If I can find out which antenna system I have, I would like to download User/Installation/Parts Manual(s).
By the way, the antenna head plastic cover is oval shaped rather than wing cross section shaped.
Thanks,
Piffery1

Assuming the "wings" of your Batwing antenna are painted white, you have the Sensar II and it is amplified and the Wingman add-on will work just fine. I don't believe your coach is old enough to have had a non-amplified antenna but those would have had silver anodized aluminum (not painted) wings.

I removed the antenna from the mast today and disassembled the snap together plastic cover. Found there is indeed a preamplifier printed circuit card in place. After cleaning much corrosion off the pc card using an electronics cleaner, I found what appears to be a part number for the preamp. To wit: 2700540E. Still no model number though. I'll do some more cleanup work and reassemble it tomorrow. Lots of dead bugs, spiders and bug residue. I'll probably coat the circuit board with a dielectric spray to prevent further corrosion and some sort of sealer to keep out the moisture and bugs. If the antenna works pretty well, I'll order a "Wingman" upgrade. Thanks,

The antenna is not meant to snap together/apart so my advice would be to buy a new Sensar IV antenna which has the Wingman build in. It's a pretty inexpensive part and will give you the performance you are looking for. It's available a local Camping World or on Amazon for about $65.
