Low and behold, despite the fact it's totally unadvertised, the HDP-269 indeed has a built in FM trap that is -12db, matching it's gain, that is fixed and always on (it can't be turned off).
Here is the email from Winegard's engineer, Hans Rabong.
My question to Hans was can the HDP-269 be used as an FM antenna system amp. Obviously it can not!
So for the last year I have been suggesting people not buy the HDP-269 that only needed a small amp, yet lived near an FM station and suggested the AP-8700, which has a fixed and tunable FM trap.
But this new information makes that moot and makes the HDP-269 maybe the best small amp out there. With it's small gain 12 db and low noise 3.0 but really shines in it's tolerance to overload taking signals as strong as minus 15 dbm according to Hol_ands chart. That is a pretty strong signal meaning it can be used in fields as strong as 60 db NM range including the antenna gain to overcome coax loss.
As a disclaimer I do have nearly instant access to Hans and Winegard does have me currently comparing a couple of their antennas. The only benefit I get from this is I get to keep the antennas. Which in this case won't do me a bit of good after the test (too small). I will be doing a lot of testing out of the car, which leads me to another post.
