substitute for antenna 300 ohms to 75 connection.

A loop of coax cable will also act as an impedance matcher for your antenna. That amp you have is a distribution amp. It is bi-directional and is made for cable. It will work for antenna but is really a cable tv amp and not for mounting close to the antenna like a pre-amp. Do you have the power supply connected to the amp? Google "homemade coax loop balun" to make a coax balun for your antenna.

Just to let the OP know, I did a test on an antenna to try to duplicate what he did. I used a junky VHF/UHF/FM signal splitter with matching balun to setup the antenna (two bay loop type Radio Shack UHF) as best I could. Then I tried just going to coax with a couple of alligator leads--I could do as well or better than the splitter, but had a signal analyser as well as signal meter on a DTV converter box to aid me and some of best signal came from making some very unusual connections.
Best results came from using a 300 to 75 ohm matching balun--on the signal meter it showed weakest channel at 35-37 and with other ways I got from 25-32. I know the signal meter does get number from SNR, so not dB but related.

aajvvh5897; of course if you use alligator leads you're going to get worse signal,you have to connect the coaxial center lead and the ground coaxial straight to the antenna,and i also ground the negative to the house utility ground,

note that i also tried to use almost same way as alligators leads as you did i had less signal.

i have the distribution amp close to the antenna in the mast inside a water proof in-casing and a power insert-er inside the house,i have now the best reception i ever had, so no need to change anything, nor pay for baluns

Maybe OTA signals nowadays won't fry your set up! Good for you.

[Frank55]

what do you mean fry,sorry i'm not English,for me; fry means damage,and my set up is i'd say about 90% ok.

these are the chan i get in perfect conditions with this set up.
