Looks like the first Tvfool report at 22 feet antenna height above ground and the 75 foot antenna height above ground are the same location and are showing the best signal strengths.
The other antenna heights of , 40 , 60 , 90 , feet antenna heights above ground are much Weaker signal strengths and different location then the , 22 and 75 feet antenna heights above ground.
The 22 and 75 feet antenna heights is what I will make recommendation for.
A small improvement in signal strength at 75 feet antenna height is shown.
The small improvement in signal strength is not worth going to 75 feet antenna height above ground , first.
Recommend install antennas at about 25 feet or more if you can do more with out jumping through a lot of hoops.
25 feet or so will be a good Test reception antenna height.

CHAN-DT Real UHF channel 31 is in between , CHEK UHF channel 49 to the North at about 353 degrees magnetic compass direction , and , KVOS Real UHF channel 35 , KBCB Real UHF channel 19 , K24IC Real UHF channel 24 to the east at about 87 degree magnetic compass direction.
For reception of the above Digital Broadcast Tv Stations/Channels , aim a Antennas Direct , DB8e antenna at about 49 degree magnetic compass direction , CHAN channel 31.
Here is how to a aim antennas ,
www.kyes.com/antenna/pointing/pointing.html
Use a Real and Actual magnetic compass to aim antenna.
------
All Testing of reception is done with a run of coax from the antenna through a open door or window , direct to 1 Tv.
No splitters.
Test reception , without and with a , RCA TVPRAMP1R preamplifier.
When testing reception without the preamplifier , All parts of the preamplifier must be disconnected , disconnect the preamp unit , disconnect the power inserter , disconnect the power supply.
-------
The Tv Must Channel scan for the , ATSC-Digital Broadcast Tv Stations/Channels , often named the ~ Antenna Channels ~ ATSC Channels ~ DTV Channels ~ Air Channels ~ in the Tv Setup Menu because the Tv transmissions travel through the Air from the transmitting antenna to the receiving antenna.
Some Digital Tv's will Automatic channel scan for cable Tv channels.
DO NOT channel scan for cable Tv channels.
Go into the Tv Setup Menu and select ~ Antenna Channels ~ DTV Channels ~ ATSC Channels ~ Air Channels~.
Channel scan for the ATSC-Digital Broadcast Tv Stations/Channels.
-------------
For Testing reception of the Much Weaker Signal Strength UHF Digital Broadcast Tv Stations Channels in the directions of , 129 , 135 , 181 , degree magnetic compass direction , kEPX ION thru to KZJO MyNetwork.
Turn the DB8e antenna to about 150 degree magnetic compass direction.
The RCA preamplifier will need to be connected.
And rescan for channels.
----------
Here are some above the roof antenna mounts.
www.ronard.com/909911.html
Use the , ronard (911) , 5 foot tripod antenna mounts.
www.ronard.com/Tripod%200703/4712.html
Use the , ronard(4712-50-10) , 10 foot tripod antenna mount.
www.ronard.com/ychim.html
Measure around the chimney and use a , ronard(2212) , ronard(2218) , ronard(2224) .
--------------
One more Tv station might be receivable , KSTW , VHF channel 11 , The CW is a long shot , if you will like to try for it the install a ,
www.antennacraft.net , Y10-7-13 , VHF channels 7 thru 13 antenna and aim it in the direction of about 135 degree magnetic compass direction.
-----------
As always , the starting antenna aim direction is the ---> starting antenna aim direction.
The antenna can aim and location can be adjusted for best reception.
Most Digital Tv's have a , Signal Strength Meter , and some Digital Tv's also have a , Signal Quality Meter.
Signal Quality is Important for reliable reception.
-------------
If reception of the Tv stations is Ok.
Then for Over All Reception I recommend 2 Separate Antenna Systems.
A DB8e for reception of the , East to North group of Tv stations.
And a Separate DB8e antenna and possibly the Y10-7-13 antenna for reception of the Tv stations from 129 to 181 degree magnetic compass direction.
The 129 to 181 degree , group of Tv stations Will Require the RCA preamp and if the DB8e and Y10-7-13 are used then the RCA preamp will be operated in the separate antenna mode.
--------------
The East to North group may or may not require a RCA preamp.
-------
Testing for reception of all Tv stations is what you will be doing.
The first 4 Tv stations in the Green reception zone are Plug and Play , the reset of the Tv stations Are Not Plug and Play.
----------
The Separate antenna systems for reception of the , East and North group of Tv stations and separate antenna system for reception of the group of tv stations from 129 to 181 degree magnetic compass direction are ,
Separate antenna systems All The Way to Each Tv Location and at each Tv location a Remote control A/B antenna switch is connected so as to change antenna systems , A/B antenna switching is Channel Surfing Friendly.
The remote control A/B switch is model number 32-4425 at ,
www.mcmelectronics.com .
www.saveandreplay.com has the same A/B antenna switch.
----------
Yes as a antenna rotator can be used and not A/B antenna switching.
However Know This , antenna rotation with a antenna rotator Is Not channel surfing friendly , must wait for antenna to rotate , and , their Will Be Domestic Situations About The Direction The Antenna is Aimed.
