Help in Western Montana.
Ok so here's the deal and this will be long. I started by using cheap bunny ears and picked up one station, so I though what the heck let's see what we can do with a better antenna. My first choice was the Antennas direct Clearstream 2-V long range UHF/VHF antenna, without doing a tvfool check. The results, I picked up NBC no problem which didn't surprise me since I can get that one with the rabbit ears, and if I angled the antenna at about 45 degrees I picked up ABC/FOX even though that one comes up as grey extreme measures needed. If I took out the angle I picked up CBS/NBC but lost ABC/FOX, and couldn't get PBS at all. So I decided to add the RCA TVPRAMP1R, this gave me a stronger signal for the above mentioned channels but again it was either CBS/NBC or NBC/ABC/FOX and no PBS either way. Next I tried the ClearStream 5 VHF Ultra long range and nothing at all, even with the pre-amp. I'm now using the RCA ANT751, which I understand is also know as the winegard EZ HD Antenna with the RCA pre-amp. I'm able to pick up PBS with a signal of 40 according to my tv screen and 70 for NBC, I can move it slightly and get CBS/CW as well but when do that PBS goes out. I know there is a spread between PBS/NBC and the rest of the stations, and probably can't get all the channels without an antenna rotator. So the main thing I want to know is it possible to get an Antenna that will at minimum pick up NBC,CBS,ABC,FOX or is what I have the best I'm going to get signal wise? Here is my tvfool report, http://www.tvfool.com/?option=com_wr...46ae259b3338d1

The signal levels shown in your report suggest you need to use a large antenna with UHF and High-VHF capability or a combination of separate single band antennas.
Given the rather extreme terrain in the Missoula area, the accuracy of a prediction may be affected. Your reception experience thus far is encouraging. Consider the Winegard HD7698P pointed at 314° per a real compass. If you have more than one TV to connect, or more than 50' of coax between the antenna and TV, add an RCA TVPRAMP1R preamplifier. A premium system would be an Antennacraft Y10713, Antennas Direct 91XG and the TVPRAMP1R. Regardless of which option you choose, the antenna(s) need to be outside, clear of obstructions. |

If someone wants to experiment with the Stacker, I won't try to stop them. The HD Stacker has it's fans and some others who would rail against it. I've yet to find credible documentation of it's performance, so I'm inclined to recommend options that have published specifications.
I just ordered a TVPRAMP1R from Amazon... less than $25. http://forum.tvfool.com/showthread.php?t=13530 I'm not impressed with any of the rotators available... until you step up to commercial / HAM grade products. If the HyGain AR-40 is within your budget, I could suggest it in good conscience. http://www.hy-gain.com/Product.php?productid=AR-40 I'm more inclined to recommend a second antenna and tuner: http://forum.tvfool.com/showthread.php?t=2882 This solution avoids any risk of being stuck with a TV that has to be re-scanned every time you switch antennas or re-aim the antenna. |

Soap Box Alert...
Amplifiers are not a replacement or substitute for the correct antenna, mounted in a location that has adequate signal quality. Signal quality is like water quality... There's a lot of water in the sewage treatment plant, that doesn't mean you would want to drink it. A weak signal free of interference and noise will be easier for a tuner to work with than a bunch of amplified noise and interference with a dab of real signal mixed in.

You're describing a situation that's quite common. Most TV signal meter functions display a value that's related to the error rate of the received signal. Simply increasing the signal level will not change the error rate if the errors are the result of signal quality at the antenna. A more powerful mix of signal, noise and interference will not be much easier to receive and decode than the weaker version.
If you get no signal through the preamp, you can presume the amplifier is not connected or powered correctly or it has failed internally. That you see signal though it says that it's working. If the total length of coax is 50' or less, and you are only connecting one TV with a good quality tuner, a preamplifier will add little. A 100' section of RG-6 will have less than 6 dB loss at the highest UHF frequency. At VHF frequencies the loss can be less than the amount of noise created inside a good preamp. |

It sounds like you have a good quality tuner. Not much to be gained adding an amplifier unless you add a splitter and more cable.

If you plan to be in areas with broadcasts on real channels 2 through 6, the HD1850 would give you just about the best available performance in that frequency range. It's a big antenna, you'd need to think about protecting it when on the road in the camper.

I think I may have misspoke or your misunderstood me. I was thinking about upgrading to the HD1850 for my home and using my RCA ANT751 on the camper. Correct me if I'm wrong but, I was told I'm in an area where I need a large direction Antenna with a preamp? I received this information from one of my local tv stations, they claim a "deep fringe" antenna will work best. So are they giving me false information on what works best for high VHF? All of my channels in Missoula are VHF except 23.1/23.2 which are ABC/FOX, and I don't really need them since I have them on my SAT. One thing really confusing me is I'm getting KUFM-TV and K14IU-D which are at 202 and 209, When I point my current antenna at 314 give or take a couple degree's in each direction I get nothing even with my antenna being 25 feet in the air. It's so confusing to me, and I'm sorry if all my questions are driving you mad, you've been patient and helpful with my inexperience.

Ah... I didn't read carefully. Your patience is equally appreciated. The ANT-751 would make a very good camper antenna.
The HD1850 does qualify as a 'deep fringe' antenna, as does the Winegard HD7698P. A significant difference between the two is that the 1850 has intentional support for real channels 2 through 6, the 7698 does not. If you know of credible talk about adding one or more translators in your area, and they are likely to be using channel 2 through 6, the 1850 would be worth the money and extra wind load area. Otherwise, I'll stick with my recommendations in post #2 of this thread. You can click on the call signs of each station on your report to see the path profile. It appears that you are severely shadowed by very tall terrain. You are no doubt needing to tilt the antenna toward the top of the ridge where the signals are diffracting over toward you. I would expect there to be sources of reflected signals also. |

Just spoke with the fine folks at solid signal and the recommended the Winegard HD 7084P, Attenuator: 1296F, and Amplifier: AP8700.

Look, you're in a deep, deep valley with granite walls 1000 to 2000' feet tall. The towers are behind the rim of the valley and all you'll ever get are reflections. Pick a very directional high-VF antenna plus a very directional UHG antenna, a rotor, and a decent sensitive preamp and start experimenting. I'd suggest either the single antenna already suggested or the premium system of a 10-element Winegard, a 91XG, a PA18 with UVSJ, and a capable rotor. Mount it all up in the air and give it a whirl. you'll get whatever is available, depending on your level of patience. |
For shot at reliable reception.
My recommendations are still the same. When setting up and testing the system , leave the antenna clamps a little loose , tip the front of the antenna/s up so the antenna is pointed at mountain ridge. When is all adjusted for best reception , then can bend the mast pipe and tighten every thing. Tv antenna rotators Are Not channel surfing friendly , must wait for antenna to rotate , and Will Be Domestic issues about the direction the antenna is aimed. Remote control A/B antenna switching Is Channel Surfing Friendly , press the button on the hand held remote control , change antennas and keep on channel surfing. |
