I had the Channel Master 45 Mile antenna up and it is 20 + years old with a missing element. I was receiving 49 FREE Channels abet some were hit in miss. The new antenna is the 100 Mile, and is a monster. Three separate sections. I was hoping this would stabilize the channels on the fringe, I went from 49 channels to 28. Not very happy, Same coax was used. I tried scanning the channels with the antenna pointing the same direction as the old 45 mile one. Any suggestions before I sell this and go back to the old broken antenna.

The new antenna is likely more directional. If so, some of the stations you no longer receive may be to the sides and rear of the antenna pattern of coverage. Any station to the sides and rear may have a reduced signal.

If you enter the information for your location at the website linked above you will be able to see where the stations are located and there coverage area. If they are to the rear or side of your antenna pattern and do not have good coverage for your area, you will have to point the antenna at those station in order to receive them.

Those big elements are only active down at the 50MHz-60Mhz TV band. Do you really have any channels in that range? Broadcasters usually abondon that frequency band as they only can use it for 2-3 channels, a waste of valuable space in the tower with the needed huge elements. It's much easier to use UHF or at least high-VHF to use the same antenna system with many more channels in the same combiner. In my country we dropped low-VHF many many years ago.
Could you change your antenna amplifier to a more noise free one to receive those fringe channels a little better?

The two big ones ABC and NBC are VHF in my area. Most of the good channels are around 75 Miles away. I was picking them up with the old antenna, but mostly in the mornings, and clear evenings. I ASSUMED a larger antenna would be better.
Coax and connectors are new I installed those with the old antenna a couple weeks ago to test the reception, I just swapped the antennas out. (Was using an old whip before) Wondering if I can place the old antenna below the new one and run separate coax and swap between the two antennas at the TV. I am running an amp also.

Those power lines are probably farther away than they look. Be careful. Try without amplifier, and see if there is any change. The amp i have has to have unused outputs terminated. Check connectors at antenna; disconnect coax and check cable for a short with ohm meter.

Can't see any VHF channels in the map, only Hi-VHF and UHF but transmit towers are in front of antenna and at the back direction and a bigger better antenna will have more screening in their back direction. https://nocable.org/availability-report/zip/76797-waco-tx
You could make use of your old antenna and point it in the other direction and combine the signal, preferable having their own amplifiers and then use a 2-1 CATV splitter. That RCA VH240R amplifier probably have a noise level of 5-6dB NF and if replacing it with a 0,5dB model are like adding 3 or 4 antennas combined or increasing one antennas size 4 times.
I recommend to:
Set up your old antenna again pointing in the back direction
Get an additional low noise amp
Get a 1-2 splitter
Test using the quality amp on both antennas and see where it does most good and use RCA on the other antenna. You could get a FM trap filter and a LTE filter as the TV could have problems with interfering signals as their receivers are of a very cheap design. If the amplifier has a higher gain than 15dB you probably have to reduce it 5-10dB to not overload your TVs receiver.

I may try what this guy did sense I have two antennas. I have the same issue, Standard channels are West, and PBS is South. Terrain is flat so little chance of multi path distortion. Too windy today to try this.

That amp might not be helping, if it is not close to the antenna. Also, if there are any competing signals, or anything causing overload.

The CM7777HD help me out a LOT
I wonder what time of day you scanned for channels and got 49. And if all of those were indeed active. I scan for channels after the sun has gone down, it will find the most, although many will be "fringe".
I've been doing some research for my own situation, and also preparing for when many stations will be moving their frequencies (and ATSC 3.0 will come online). I have stations in just about every direction with varying power levels. Make sure to focus your antenna toward the main stations you wish to receive.

Any ideas on overcoming the problem of being in the middle of an oak forest? 60’ tower on site but trees are 80’!

Seriously, using a larger outdoor antenna, mounted on a rotator.
Channel Master has this model, for UHF & VHF-hi:

If you want VHF-lo:

You can't amplify a signal out of the background noise. If you now have some signal but a lot of noise in the picture or digital artifacts you could get a low noise amp less than 1dB NF. If it works ok during winter time when the leafs drops off it might be possible to improve the signal strenght with a better amp or you could add a satellite receiver.

I currently have something similar to that masterpiece 100 on a rotor. Unfortunately, when I came in at in one direction and use the auto scan feature on my TV, it stores the channels in that direction. When I swing the rotor in another direction to get other network channels, I have to re-scan and then it loses the channels in the first direction. I was thinking of installing two amplified antennas similar to this and coupling them:

There’s a million of these under just as many names with just as many prices that all use the same picture. Anyone know if they are any good?:

every ATSC device I have worked with has a "add on scan" or "digital add on scan"
that way you wont lose your results

Yes, it should at least be a channel function to let you manually add channels. Write down channel numbers from one direction and then search on another direction and manually add the channels that do not show up from your note.
The Televes products are good. A friend has one and most neighbours complains on bad reception and the installers set up different antennas but it didn't help. My friend bough and installed the Televes for one neighbour and no problems since then. Never trust gain figures as the important thing are the relation between signal and noise s/n. The Televes use an amplifier that has a 1.6dB noise figure which is excellent. If you have the same antenna without amplifier and add your own that has 0.5dB noise it could be even better but then you don't have the special solution from the Televes one that reduce ignition noise and other interferencies.
$25 antennas are useless. The one you refere to have one dipole for VHF/FM band and 5 elements for UHF which doesn't give enough signal strenght to an amplifier to work with.
