Please Advise on Antenna Type

Hello,

I'm looking to purchase an outdoor antenna, but am not sure which ones to look at for my particular needs. I'm hoping to get as many channels as I can, so I'm thinking I'll need one that is multi directional. There will be 2-3 TV's hooked up to it. Am on a bit of a budget ( $100 ). Any advice on which antennas I should be looking at? Not sure about amplifiers and tuners, would appreciate suggestions there also. I attached my TV Signal Analysis Results.

Thank you

Welcome to the forum, Bewitched:

Thanks for the tvfool report image. Which zip code did you use?

It would be better if your report had been done using exact address or coordinates, which will not show in the report. Because of the hilly terrain in Olympia/Lacey, a more exact report is needed for a good analysis. If you can, use a more exact address with the regular page here:
http://www.tvfool.com/index.php?opti...pper&Itemid=29

The estimated report for your location is very different than your image report. The signal strengths are very different, but the distances and azimuths are close:

If you can't use an exact address on the regular page, you can go to the interactive map feature here and move the map cursor to the antenna location, enter the antenna height below the map, and click on Make Radar Plot above and to the right of the map:
http://www.tvfool.com/index.php?opti...pper&Itemid=90

Please post an active link for your report instead of an image. You will find it near the top of your report in bold type. We will then be able to click on a callsign to see the terrain profile between the transmitter and your location.

Tell us where your antenna will be mounted and how long the coax run to the TV will be.

Will there be any trees in the signal path?

The solution to your problem will be a little difficult because you have channels in different directions with different strengths, but we will try to keep your budget in mind.

That's a term that is used by the marketing department, not engineering. With your weak 2Edge signals for ABC and NBC, the antenna should be aimed directly at them.

Okay, I redid it with my exact location. http://www.tvfool.com/?option=com_wr...82304352b902a3

About my area: I am up on a pretty high hill. There will be some large leafy trees in the path. I plan to mount it outside on a pole as high as possible, and as clear of the trees as possible.

There will be about 10ft of cord to the first TV and about 30ft to the second.

Yeah, I've been concerned about the station locations.

Thanks

Thanks for the tvfool report. It is more promising than the first one going by KING NBC real channel 48 which is the weakest that you will probably want.

Ah, 98503, thanks. I ran all the zips and that was the closest, but it didn't quite match your image report.

Most of your signals are UHF real channels; many at 10 to 13 degrees magnetic. You will probably need to aim for NBC. There are 2 VHF-High channels: KCPQ Fox real channel 13 is at 342 degrees magnetic, and KSTW CW on real channel 11 at 13 degrees magnetic.

You might try a Winegard HD7694P VHF/UHF combo aimed at 10 degrees magnetic to see how it does on one TV without a preamp. If the signals are too weak after splitting, you can add an indoor distribution amp or an outdoor preamp, but not both.

2Edge signals need a little more antenna gain; I hope the 7694 has enough. The next step up is the 7697.

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.

You have some strong FM signals that might cause interference to TV reception; see attachment. You might need an FM filter.
