Any hope for using an antenna at this location?
Signal Analysis results
If so, model & height recommendations please.

Yes you will have very good reception. How many Tv's will be connected??

I must say that answer surprises me since it is over 60 miles to Orlando transmitters & over 70 miles to all but 2 West Palm Beach transmitters.

There will be 2 TVs connected.

True, but many of the stations have signals that are fairly powerful which works in your favor.

Your report indicates mounting an antenna at 40' AGL. That explains the optimism for good reception. If you can not actually mount that high, you may be disappointed. (I wish I had a 40' tower...)

Presuming you can mount at 40', clear of trees, I would recommend going for the Orlando stations to the NW. I would pick a large high-VHF/UHF combo antenna like the Winegard HD7698 matched with a quality pre-amp such as an HDP-269.

I would hope to see stations as low on the report as WOPX and WTGL.

An alternate solution would be a 91XG (UHF), a Y10713 (high-VHF), combined with a CM7777 preamp (with the FM trap engaged).

The Digital Tv Channel Signal strengths at your location are Ok. The situation at your location is the adjacent channel warnings and co-channel warnings , most of them are Analog Tv channels that can cause possible interference to Digital Tv channels. In Florida the FCC can put more pressure on those analog stations to switch to digital. Read and understand this about Real Digital Tv Channels and Virtual Digital Tv Channels , http://forum.tvfool.com/showthread.php?t=695 . Ok the Tv antenna is a Winegard HD7698P with a Winegard HDP269 preamp mounted on the roof or a tower and pointed at 334 magnetic compass. This antenna is sharply forward directive so as to reject interfering signals on the sides and back of the antenna. I do not expect there will be a problem with interference but won't know until yea try it. Here is how to aim Tv antennas http://www.kyes.com/antenna/pointing/pointing.html The 40 feet you have for antenna height is fine. Do you have newer model Digital Tv's ?? Or will you be using Digital to Analog converter boxes??

These are the Digital Tv channels to the north west that are in your reception range. WFTV 39 ABC , WMVJ-CA 29 Telemundo , WKMG-DT 26 CBS , WKCF_DT 17 The CW , WTCE-TV 38 Indpendent , W32DJ-D 32 3ABN 3 Angles Broadcasting Network , WOTF-DT 43 TeleFutura , WRBW-DT 41 MYNetwork , WOFL 22 FOX , WESH 11 NBC , WDSC-TV 33 PBS , WMFE-DT 23 PBS.

And so that you will know , in the other direction about 170 degree magnetic compass these are the receivable Digital Channels , WPBF 16 ABC , WTVX 34 The CW , W31DC-D PBS 31 - maybe identified as WXEL 44 , WWCI-CA 10 Independent. Here are online Tv Guides , http://television.aol.com , http://tvlistings.zap2it.com , http://www.titantv.com . .

At the >>Start MAPS<< part of tvfool I put in 20 and 30 feet as antenna height and still looks good for reception.

Daiwe01 · 24-Jan-2011, 3:14 PM

Thank you guys for your efforts!
GroundUrMast -

I linked the wrong analysis (40 ft). 20 ft. Signal Analysis I can not get as high as 40 ft.
Using GroundUrMast's "lower limits" of WOPX & WTGL, at 20 ft. they are still marginally positive NM at 5.3 & 3.4 dB with Power -85.5 & -87.5 dBm. Is the signal NM the probable determinant with the low Power requiring the pre-amp?
What other site/book should I read to begin my education at the Novice/Dummy level?

John Candle · 24-Jan-2011, 3:37 PM

As I stated above. At the >>Start MAPS<< part of tvfool I also ran it at 20 feet and 30 feet. The differences of 7.4/5.6 and 5.3/3.4 is ---- 2.1 and 2.2 , not much of a difference. 2 NM (dB) in this situtation will not make any difference of receiving the channels or not receiving the channels. GUM got his suggestions in before me , but then what do I know.

GroundUrMast · 24-Jan-2011, 4:43 PM

I am not concerned about mounting at 20' AGL now that you and John have checked it.

Here is a link to one of many installation guides... http://www.starkelectronic.com/cmig1.htm It is a multi-page read, be sure to look for the 'next' link at the bottom of each page.

WDSC-TV 33 PBS , WMFE-DT 23 PBS , WSCF-LP 20 AMG Tv verity programing , WACX-DT 30 PBS , WRDQ-DT 27 Independent Tv station , WHLV-DT 51 Religion , WOPX-TV 48 ION Television , WTGL-DT 46 Independent Tv station. All of the channels to the north west need a boost and these weakest ones need a boost , however not to much the HDP269 has about 12 dB of gain and thats not much , however it's a balancing act , keep the interfering channels at bay. Starting with WACX-DT and on down the weaker signal strength will make it more likley that the adjacent and co-channels will have greater effect on the channels , if the channels are received fine , if not fine.
