You might try to split the difference, but, channel 33, (3) has a NM value of only 1.8 and it's a 2 edge so you may never get it without a large old school VHF antenna. (If then.)

Real 33 is WPXG (ION) Which is on the back side as ADTECH mentioned. Without using a tinlee or a rotor or separate tuners... I highly doubt I'll get it. I don't need the channel I'm happy with it.
Channel 11 is another PBS and I already get 2 other PBS stations so I'm ok with not getting that one as well. The VHF are Di-pole's... I'm not sure it has any gain is any direction.

WORK-LP is presumably still operating under their STA at a measly 58 watts ERP while they wait out the FCC's spectrum actions. That meager signal will never make it to this location.
You would improve your system noise margin by at least 2 dB if you put the amp immediately at the antenna as is customary.

What would installing the FM traps after the preamp do? The FM trap don't appear to be very weather proof. lol
