Need help selecting antenna

Looking for outdoor rooftop antenna, but lots of choices and I'm new at this. I have clear line of sight except southeast (trees) from the roof that is 30 ft above ground. Also splitting to 3 tv's.
My report: www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d5b9415a54fe765
Would like to receive the 4 main networks:WGAL, WHTM, WHP, WPMT
Don't know if WPMT is possible
I would appreciate any suggestions you might have, thanks in advance. Lots of good information here, learned a lot already!

WPMT Fox will not be received.

WHSV-TV Real UHF channel 42 , has , ABC , FOX , MyNetwork , Me-tv.

WHSV , signal strength is very weak at -7.2NM(dB) and has 2 Edge Path obstructions = reception path obstructions = hills/mountains.

To see if higher antenna height will improve WHSV signal strength please make and post 2 more tvfool reports , 50 feet , 75 feet , antenna heights.

-------------
WHP-Tv Real UHF channel 21 CBS is very weak signal strength and will not be received because WVPY Real UHF channel 21 PBS is a stronger signal and will override WHP.

-------------

With the increased antenna heights , perhaps WHP - CBS will be strong enough to receive.

And I can recommend a way to reduce and block WVPY - PBS.

Please make and post the 50 and 75 feet antenna height reports.

I can then make a recommendation.

Well I can make a recommendation now , however will be nice to see the higher antenna height tvfool reports and I can make a better recommendation.

For reception of the easy to receive Digital Broadcast Tv Stations/Channels with the Tv antennas at about 35 feet above ground.

WHAG-DT , Real UHF channel 26 , NBC.

W42CK , Real UHF channel 43 , Religion.
WHTM-DT , VHF high band channel , 10 , ABC and RTV Retro Tv Network.
WAZW-LD , Real UHF channel , 46 , Religion.

--------

Above the Peak of the Roof in such a manner that reception is not being , obstructed , impeded , blocked , by the roof and building in the directions of , South West , North , North East , East.

Install a , Antennas Direct , DB8e UHF channels 14 thru 51 antenna aimed at about 217 degree magnetic compass direction.

And install a , http://www.antennacraft.net , Y10-7-13 , VHF high band channels 7 thru 13 antenna aimed at about 67 degree magnetic compass direction.

Here is how to aim antennas , http://www.kyes.com/antenna/pointing/pointing.html.

Use a Real and Actual magnetic compass to aim antenna.

Install the , Y10-7-13 antenna about 3 feet below the DB8e antenna on the same mast pipe.

--------

Here are some above the roof antenna mounts.

http://www.ronard.com/909911.html.
Use the , ronard(911) , 5 foot tripod antenna mount.

http://www.ronard.com/Tripods%200703/4712.html.
Use the , ronard(4712-50-10) , 10 foot tripod antenna mount.

http://www.ronard.com/ychim.html.
Measure around the chimney and use a , ronard(2212) , ronard(2218) , ronard(2224) .

Buy the ronard antenna mounts at , http://www.ronard.com , or , http://www.amazon.com.

---------

Home Depot and Lowes have 10 foot long sections of , Top Rail , chain link fence Pipe that makes good antenna mast , the price is Low Dollars.

---------

Install a , http://www.antennacraft.net.

10G221 preamplifier.

Connect the DB8e UHF antenna to the , UHF connection of the preamplifier.

Connect the Y10-7-13 antenna to the VHF connection of the preamplifier.

The FM radio trap switch will be in the , in/on position.

---------

For Initial reception Tests have only 1 Tv connected.

Run a Continues length of RG-6 coax through a open door or window direct to 1 Tv.

The Tv Must Channel Scan for the , ATSC-Digital Broadcast Tv Stations/Channels , Antenna Channels , Air Channels.

DO NOT channel scan for cable tv channels.

--------------------------------------

WHSV-TV , UHF channel 42 , ABC , FOX , MyNetwok , Me-TV , At 217 Degree magnetic compass direction , is Very Weak Signal Strength , even at the 50 and 75 foot antenna heights , WHSV will most likely not be received or received reliably.

You can raise the antenna height with the Top Rail Pipe for Testing of reception.

---------------------------------------

With the 10 foot sections of Top Rail Pipe you can raise the antenna height higher , if required , above ground , and aim the DB8e antenna at about 68 degree magnetic compass direction to Test for reception of , WHP-TV , UHF channel 21.

Will need to rescan for channels.

Most likely , The stronger signal strength , WVPY UHF channel 21 , will interfere with reception of WHP , even though WVPY will be at a back angle to the DB8e antenna.

----------------

As always , trees and tree leave , plants and plant leaves , have a Negative Effect on Broadcast Tv Reception and so do buildings and other obstructions including your own roof and building.

Some and not all Negative Effects are.

Absorbing and Blocking Reception.

Multi-Path Reflecting Tv Signals Bouncing All Around.

The Best Practice for Reliable Reception is to install antennas at a location that has least amount to no amount of obstructions of any type or kind in the directions of reception including your own roof and building in the directions of reception.

The directions of reception at your location are , South West , West , North , North East , East.

Thanks for all the great information and your time. Keeping my fingers crossed on receiving WHSV or WHP but I'll take what I can get. Looks like snow next week, so I'll have to wait to go up on the roof
