^Maybe it's related to changed they implied needed to be made in order to accommodate grit TV.

Though it doesn't bother me, not everyone is comfortable with wiring "live" circuits.

OK, I'll bite. What does the acronym, EIT, stand for in this context? In every company I've worked for EIT stands for Engineer in Training.

I've always seen program guide info referred to as PSIP (Program and System Information Protocol) or EPG (Electronic program guide). I hadn't run across EIT used this way before.

EIT does stand for engineer in training. It's one of the grueling steps that you have to get through, at least here in NC to be allowed to sit for the PE. Best taken when you completed your sophomore year of a BS in Engineering program, but of course they won't let you do it then.

However in the context that I used it in, EIT is PSIP info. sent out by the stations. I'm not one to use industry lingo to obfuscate a conversation so my apologies. I thought it was a common term, but that doesn't appear to be the case. MythTV refers to it in this manner when you decide if you want to use it or not.

^Reminds me of when I worked for old Bell System. Acronyms ruled the day there in telephone land. Interestingly, however, and it's the only place that I've seen it, they would constantly tell the employees NOT to use these terms with the public. They didn't want customers confused by technical jargon. It's something that has stayed with me all this time. IMO, it's a practice that should come back.

Though when I worked at the Bell System employee relations had a different meaning. http://www.telephonecollectors.info/...her-jones-1981
It was a sad day when they had to lock up the green pills.

It's fascinating to see the effect that weather has on a marginal signal. Concerning the antenna that I built above, it was designed, "cut", specifically for RF 15 which happens to be WNSC in Rock Hill.

  • In the middle of the night, it does get enough of a signal to hold a lock on WNSC. However as soon as the sun starts to come up, it's gone. It won't even scan.
  • The LNA 200 amp has no effect on this or anything else the antenna picks up in this area. It's proof enough that an amplifier doesn't make an antenna receive better.
  • It absolutely won't pick up RF 11 or WTVI. Proof enough that if want VHF you should get a VHF/UHF combo.
  • On the other hand, it as an amazingly wide beam. For the stronger UHF channels that I get, it really doesn't matter where the antenna is pointed. It will receive them. Most like this has a lot to do with the entire antenna being electrically connected rather than to make the dipole and reflectors/directors insulated from each other.

Think I'm going to build a bigger one to replace a 4 bay.
