Thanks for the additional information that you tried the HD8200U at 8ft. above ground not at roof level. Also thanks for the information about you vanity, your neighbors are more important than your reception.
My hope is to first establish whether there is any hope for reception.
Using just your zip code, it shows that you're 55 miles away with a middle of the road signal. I don't know if a dipole is good enough without some help from additional elements.
i am willing to add a reflector and director. what material would you use to makea folded dipole?
Yes, at ground level, no roof. all my neighbors are really good people. I get along with all of them. Question, why use 54Mhz and not 57MHz?
i did register on tvfool but cant post anything. tried following directions, and still cant post

I'd use material that would likely cost me more than buying a professionally engineered off-the-shelf broadband antenna. This doesn't begin to contemplate the labor involved in constructing and tuning the antenna for best SWR.
Of course the biggest downside to making a single-purpose antenna is that we're likely to see stations moving about due to the repack and the introduction of ATSC 3.0. We know that at some point KJWP is going to have to add their ATSC 3.0 broadcast on another frequency entirely. It could be some time, but it will happen. In the interim, who knows that deals they may have to make to survive the repack.
off this post, but i would like to see all subchannels go to a nice high powered Ku band. The main local channels 14-31 for maximum picture quality and sound.
The whole point of subchannels is to deliver more local advertising to local eyes and ears. Satcasting doesn't lend itself well to the interests of local stations (outside of any carriage revenues that they might be able to extort).
i wanted say thanks for rabbit73. he was very helpful and seems like a nice person.
thank you all for helping me try to figure out KJWP and powerline noise. i am going to redo my antenna and contact the power company. i will report back with a update with in a week or 2. thank you everone.
UPDATE: I call the electric company and i felt like i was getting the run around without know 100% that it was the outside power lines. So i bought a SDR (awesome, RTL SDR) and checked 54-60 Mhz with stock SDR antenna and found AM radio.Shawn Hannity, was on one station. No matter the direction of the SDR antenna AM radio still was Any thoughts would be appreciative.

Perhaps we need to start at the start. What stations are you trying to listen to or watch? You've started somewhere in the middle without laying any of the groundwork.
You're not going to find AM radio signals in the TV band anymore. What audio signals there used to be back in the day were FM and the video signals were AM.

He was trying to pin-point a possibly electrically noisy power pole using an AM radio as a direction finder. However, he seems to not have understood that Rabbit73 on the Tvfool forum suggested using an old school portable AM radio, that still has the old ferrite loop antennas for that purpose. I know nothing about SDR's, but I don't think they'll work for this purpose. Not that you can tell for sure from his reply above what he really discovered, that seems to be oddly truncated...
i have used an AM radio just not with a loop antenna, there are server poles that indicate power line noise.
maybe i am misunderstanding the SDR, but i can listen to AM radio in 54-60Mhz range.
