Tks both of you.
styxfix - I considered the "dead spot" possibility and I will make some moves. I need to come up with some kind of portable mast in order to do that. I think I have an old 15' telescoping mast rusting away somewhere - I need to dig that one out. I can lean it against the house for simple trials. First I'll replace the cable and leave enough slack for experiments. Once I find a good location / height then I can replace everything with something shiny and new (and better able to be grounded!) Fortunately there are no power lines within 100'.
Rick0725 - Tks again for your input. I guess I went with the crowd on the 4228. If I can't get it to work out well, I have no problem unloading it and trying something else, like one of the numerous Winegard 'tennas you work with, or perhaps that 91XG from AntennasDirect ralfyguy likes so much. That one would be last on my list due to its price, but given my investment so far, what's another couple C-notes? And I definitely need HD OTA. I won't get it from E* (or D* for that matter) for quite some time!
I definitely have interference problems with the old analog signals - from nearby electric fences! I actually have two V/U antennas up. The original CM one (no model no. known) is wired with no preamp and RG-59 and it has the most interference. The RS I added with a high-gain B-T preamp wired with 6QS has less noise in the analog signals. I know it's not apples-to-apples, but it does make me think the QS is probably better for my OTA system. Besides, it's only a 1 time hassle getting the connectors on.
Regarding the distances, well I'm kinda right on the edge of the figures you mentioned. I'm definitely not suburban, more rural! With the exception of a couple of low-power repeaters in the opposite directions, my closest towers are those located on Wopsononick Mountain at about 245 deg. magnetic and 25 miles. The channel 10 antennas are there: 10 analog, 32.2 digital; I get the analog channel reasonably well if a bit ghosty and I have so for many years. So multipath is an issue where I am and I thought the 4228 is a bit more selective based on others' comments. Apparently your experience is different. I can fine-tune the RS antenna with the rotator, but that doesn't currently help with the 4228.
I think I will get the 4228 higher on a movable mast and connect a UHF analog TV to tune it for best reception on Ch 23 (same origin), then fix it to try to get the digitals I mentioned in my OP. A real bonus would be if I can get ch 6 (I get the analog very poorly) which is 34 digital and about 55 miles at almost the same bearing (243 deg.?)
Regarding my "system", well it's quite convoluted. My HD set-up is located on the opposite end of the house from where all the antennas and dishes are located. The cabling runs through the rafters in the basement to about the middle where I have power and the PS for the B-T preamp and two distribution amps. (The 44 switch is closer to the outside wall where the sat. cables enter.) From there cables go all over the place, including one sat. and two OTA cables (all RG-6QS) through conduit to the location where the HDTV/622 system is. The run from an antenna or dish to the equipment is about 40', and from there it is another 40' to the HDTV/622 location. I eliminated all splits and amps, etc. for the initial trial (using 59/59/6). I will replace the 59 so I have just two lengths of 6 and a single barrel for the next experiment. Then I will splice-in a preamp if needed, as I expect.
Since my closest channels are 25 miles and 35 miles away (PBS is at about 320 deg. magnetic) - do you think I really need the high-overload capability of the 269, or can I benefit better with the higher gain of the 8700? (I have a variable attenuator available if I need it.)
As always, your input is greatly appreciated...!
