Winegard Fitment on Older Sensar

[Zoom45]

I have a 1988 Ford E350 Class C (Holiday Rambler) that has a Wineguard Sensar amplified antenna on it. I ordered a Wingman antenna to add on but it doesn't fit my Sensar. The new Wingman came with an instruction sheet that says its for 1990 and newer models but I didn't see that on the AMAZON add. Can I still mount it on my model and it work? My manual says its a Sensar rvh-20ka-rva-30a. It looks the same as the ones on the Wineguard website but the Wingman holes don't line up and mine only has two rubber bumpers on the bottom to remove where it looks like 3 are on the ones shown on the website. There's no wires to hook up. It just looks like the antenna is mounted to the bottom of the Sensar base to hold it in place. I hate to return it if I can still use it even if I need to modify the mounting of it.
Thanks,

Thw Qingman is simply a "reflector" which helps direct RF signal to the antenna head.

The mounting holes for the rubber feet would be the only difference.

If you can get it attached, it will work.

Just drill the same size holes, where the new ones mount.
Then attach the wingman

Got it mounted. It doesn't pick up any more channels but all channels it does get is clear. I was getting 15 from my driveway before installing and only get 15 after installing the Wingman. I have 9 transmitters within 60 miles of my house.
