So I finally received the RCA PreAmp after amazon taking 14 days for a delivery... gees..
Anyway so last night I installed the preamp and added some things to the antenna.
First I added aluminum foil to the reflector and left a gap open between the dipoles at the center. The foil is thick.. well for foil its thick its renolds brand.
Also I removed the electrical tape that was wrapping the copper lines to the dipoles and replaced it with aluminum duct tape. I hoped that would provide a better connection than just the loop and screw of the copper and the electrical tape. I figure it can't hurt. I burnished down the aluminum duct tape really well and gave it about 4 wraps of it.
Anyway my results after the amp were somewhat disappointing. I do receive quite a few channels when they want to come in and i don't get cutouts or fragments when things are good.
I was working overnight and had mixed results as I worked on the antenna.
I should Add Weather.com sat image .. no clouds here for 200 mile radius all night.
Its accuracy seems to be off and random. This might be because the reflector is flexing or the dipoles are shifting but I can't say.
It could also be because the antenna is in my garage however I broke out my esky antenna and it had good directional control and lined up well with the magnetic north towards philly.
Although I point towards philly I am also getting wmar to the south of me. It could be rear gain that the antenna reflector is not stopping.
WMAR 38 real 2.1 virtual 14.3NMdb -76.5Pwr(dbm) distance 59miles at 273° south when the antenna is pointed to 30° north.
Whatever the reason its an ABC affiliate and one philly station channel 6 actual and virtual is the reason I made my dipoles longer but I do not pick up vhf from philly with this or my esky $30 antenna.
I would say the antenna I built with the RCA 20uhf/12vhf amp connected does do better than the esky but the results are not quite enough to get dependable viewing all day long.
For one thing about sun up most of my stations flake out.
They are either gone completely
require repositioning of the antenna
or in and out as they want to be.
I understand this does happen at sun up and dusk but its a problem that needs to be addressed.
The station I want to watch primarily is Fox Philly which is 42 real and 29.1 virtual and it has 29.1 .2 .3 three stations from foxphilly. It has good long morning news show from like 5 to 9 and lunch dinner and 10pm and has some good shows and some sports.. so I would like to have it.
Overnight Fox 29 comes in pretty well as do the subs at about 5:30am it started flaking out and I couldnt get it back eventually i had to stop for the night.
My TV doesnt have a signal strength indicator that I have seen/found.
umm trying to remember what else ... its been a long day.
WXTF Fox is Real 42 virtual 29 signal is 30° magnetic
TV Fool is showing I get 16.8 NM(db) -74.0Pwr(dBm) at my home
I have the 20db Amp and tried both fm trap on and off I guess On would be fine because I don't want to use this antenna for radio.
The Co-Channel warning is from
WMPT PBS 42 real Virtual 22.1 signal is 263° magnetic
TV Fool is showing I get 2.7 NM(db) -93.6Pwr(dBm) at my home
The cochannel never shows up in a scan.. the FoxPhilly when signal lock is obtained never shows fragmentation or cuts out unless the antenna is moved or something.. its a good HD signal.
It seems like If I had just a wee bit more power scotty I would be getting all the stations all the time..
Anyway thats my update for now.
