I did receive analog signals on channel 25 and channel 45, but I'm not sure what channel 45 is....antennaweb shows a channel 45 in leesburg, but that is 80 miles in the opposite direction that the antenna is pointing. I was receiving a very fuzzy analog picture from WAWS, but again, nothing digital. I will continue to monkey with it, but I guess ttl is far enough north and west of me to make a difference. However, I have all the gainesville area digitals locked in with full signal strength, which was really the goal anyway.
If you live in NW G'ville, aim it ENE to NE, that's the best direction I get the Jax stations from. The 4228 has a pretty wide aperture so just a general aiming is all you need really. Usually when analog 25, 17, and 30 comes in is when I start getting the digital stations. The order they show up for me (as the night comes on) is WJXT-DT, 4.n(42) and WTEV-DT, 47.n(19), then WJCT-DT, 7.n(38), WAWS-DT, 30.n(32), WJWB-DT, 17.n(34) and WJEB-DT, 59.n(44). Seems to me that I once received WTLV-DT, 12.n(13). I have never received WPXC, 21.n(24) or WJXX-DT 25.n(10) even though I've been told they are broadcasting.
You may want to try it without the preamp. Problem is you are amplifying "noise" as well as aimed directly at ch 5's tower and amplifying already strong ch 5, ch 36 (5's DT), FM stations, etc. So try it without the amp or get ch traps or a bandpass filter for just UHF.
If you are aiming it through the roof as opposed to the gable, the signal is greatly attenuated. Try aiming out a gable or mount it on the outside of the gable. You may have to go up on a pole to get reliable reception. If you have a lot of pine trees you are aiming through, they also attenuate the signal quite a bit.
Ch 45 is WYPN the local UPN station that appears on cable 10 or 11.
