<pre class="western">I would just add a couple of things to the excellent write up that Stephen
did. If the problem is too much signal, you can get attenuators that you
put inline with the antenna feed. If the problem is not enough signal, an
antenna outside high up is better than one in the room with the TV. If the
antenna is a long way from the tuners, an amplifier near the antenna is
what you want.
<font face="Abyssinica SIL"><font style="font-size: 12pt" size="3">Yes, agree Stephen did an excellent write-up! Here have tweaked the systems with amplifiers and attenuators to compensate for the splitters. Have removed amplifiers (worse!), tried different amplifiers (the HDP269 seems to be best), attenuated the signal (3 dB, 6 dB) at both ends of the feed (nope!)…. </font></font>
There are also different grades of cable and the cheaper ones are
not very good and can "leak" signal and pick up interference. This is more
important if you don't have an antenna but get tv through a cable
provider. The leaking cable can pick up OTA signals and really mess up the
ones in the cable as they are at the same frequency. You might even pick up
enough of your station that it cancels out the main signal but that is not
very likely.
<font face="Abyssinica SIL"><font style="font-size: 12pt" size="3"><chuckle> Not at you but back around 1980 when Cox Cable was stringing coax for this area they used cheaper coax (maybe RG/59/U). All went fine until they started stringing coax near the antenna farm a couple miles from the house – leak city!! At the time Chs. 4 and 6 were VHF and Cox rebroadcast on the same frequencies and massive interference! Ended up Cox had to rewire a portion of their distribution system with a much better-shielded coax. <u>Any</u><span style="text-decoration: none"> </span><span style="text-decoration: none">leakage in houses also created problems.</span></font></font>
Connectors are important as well and the best ones are pressed on with mildly expensive tools
<font face="Abyssinica SIL"><font style="font-size: 12pt" size="3">Right: I am using the compression connectors and have my own tool.</font></font>
I am not sure if anybody uses "twin lead" any more but that is fine as long as it doesn't run over any metal. It doesn't last as long though and I think is pretty much out of favor.
<font face="Abyssinica SIL"><font style="font-size: 12pt" size="3">Last time I used 300Ω twin lead was to make my own antenna, probably in the late 70’s. </font></font>
<font face="Abyssinica SIL"><font style="font-size: 12pt" size="3">Thanks for the suggestions and reminders!</font></font>
