Need help with some questions
Just a few questions:
Current signal plot: http://www.tvfool.com/?option=com_wr...8e039018d29295 We currently have an HBU-55 + RCA TVPRAMP-1R mounted in the backyard about 13 feet up. (previous thread for reference: http://forum.tvfool.com/showthread.php?t=14839) 1. Recently the woman of the house expressed her need for KSTP news (rf 35) is there a effective way to make that happen (with out going too crazy)? (Avoiding city hall to get a building permit is a non-negotiable, as is attaching anything to the house's exterior or attic.) 2. With the coming FCC re-pack would it be prudent to look into an antenna with VHF-lo capabilities? 3. WCCO (rf 32) was coming in about 70% of the time through the summer and fall but now that the leaves are mostly gone the signal has become quite hard to receive at all despite the Indian summer this year. Does anyone have any ideas on why? 4. How is the local cable co. (http://www.ntec.net/NtecCable.php) allowed to get away with not offering a OTA replacement package, per FCC? Thanks |

What channels do you get now? Where is the antenna aimed? Does she want that ABC station for local news instead of WQOW? Quote:

From EAU/LAX: WQOW & WHWC- LOS'esq stable, both are usually received when aimed in any direction (WHWC can be caught with a pair of set top bunny ears), WEUX- stable, WEAU- stable (despite the plot saying it is nearly impossible to receive), and WKBT- unstable, only seen when it is below freezing.

I'm running out of ideas. There are few more things you can try; no guarantee:
1. Raise the antenna higher 2. Try another location in the yard with a temporary mast; you might find a hot spot if you are able to monitor signal strength 3. Try another preamp like the Channel Master 7777 4. Make sure the coax shield is grounded to reject any electrical interference If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge, but the system will not survive a direct strike. http://forum.tvfool.com/attachment.p...9&d=1441917363 |
Greetings,
This is a tough situation as Rabbit articulates. If I were in your position, I would raise the antenna as high as I could and take a two antenna tact separating the bands out. Being Minneapolis is so weak and in 2 edge conditions, especially on UHF I would purchase an Antennas Direct DB8e and point it magnetic 299 for UHF. For VHF, I'd continue with HBU55 at the same heading. The HBU55 was a nice antenna, but when it comes to 2-edge UHF with very weak signals the most aggressive UHF only design is best employed. The HBU's UHF ability is somewhat less than the DB8e, especially if the signal bounces around a bit. I would combine both signals at the mast, then feed the combined lead into the already suggested Channel master 7777. The RCA preamp is good, but you need the most aggressive on the consumer market. If the trees are in your path, anything you do to get above them or reduce their blockage will increase chances of better reception. UHF especially is prone to being reflected by branches and foliage. It's not unusual to see trees obliterate strong signals to the point of non-reception. You might also call and ask to speak to WCCO's engineering staff. It is possible they are operating at reduced power. It's always a wise step to make sure they aren't experiencing issues before you tear your system apart. In short: Antenna 1: Antennas Direct DB8e (UHF) mounted at top of pole Antenna 2: HBU55 (VHF) 3 - 4' below of DB8e Combine signals via EU385CF VHF/UHF combiner Channel Master 7777 preamp. With this said and you signals being in the single digits to negative digits, don't expect perfect reception. Atmospheric fluctuations may make these signals come and go. My weakest signal is at -82dbm it fluctuates in strength during the day. I keep it in my Samsung 99% of the time. Yours are even weaker that that. Thus, some pixellation and drop outs the UHF signals I would expect. KTSP would fall under the paragraph above with this setup. In theory, you could get it up to a decodable level. However, I wouldn't expect it to be 100%. Go wave the clause the FCC says you can install a roof antenna without repercussions. Challenge the Association on this. Bottom line you must elevate the antenna(s) to improve your chances. Your weak signals require every bit of assistance they can get. Cheers. |
