Does anyone know if cable and satellite signals will pass thru these boxes, assuming the box has the pass thru feature?
Like most of you, I would like to reduce wiring by installing the box between the video control panel and each TV, but I don't want to eliminate or distort the signal to the TV.

If the box has analog pass thru then it should allow antenna pass thru. As far as satellite I doubt it since that requires DC pass through also....

I don't see why they wouldn't. Both your cable box and your Sat. box are converting their signals to analog. As long as your DTV box has analog pss-thru you shouldn't have any problems.

That DC voltage is on the other side of the Sat. box. DC gets passed from the Sat box to power the LNB. There is no DC voltage between the Sat box and the TV Set.

I haven't tried it yet, but the "output to TV" coax connection on the satellite box should be able to transmit signals through a DTV converter box that has the analog "pass-through" feature (my 2 for the bedrooms at home do. We have an LCD HDTV in the den and in the TT, and don't need converter boxes for them) Just remember that both the satellite box and converter box will probably have channel switches on the back that will control which channel on the analog tv that the signals will show up on.

Just remember that both the satellite box and converter box will probably have channel switches on the back that will control which channel on the analog tv that the signals will show up on.
For my bedrooms, I run signals from my 2nd sat receiver, DVD, and VCR through video switch boxes to each bedroom via one separate coax to each bedroom (the "antenna" signals are connected to, and come from,the "pass-through" feature on the satellite boxes.) The satellite "out to TV" and "antenna" signals go through the video switch boxes fine, but since they are all connected to the #2 satellite receiver, all the bedrooms have to watch the same channel (we're empty-nesters, so this isn't a big problem for us).
The #1 satellite box feeds into the den tv in the same entertainment center via component video cables, and doesn't run through the video switch boxes. It uses an infrared remote in the den. The #2 satellite box for the bedrooms is also located in the entertainment center in the den. It is controlled via an radio-frequency (RF) remote from any room in the house.

Ok, if, and I stress IF the box has analog pass through, then cable and the output of a satellite receiver will pass through no problem.
THE LNB line however (The sat receiver INPUT) needs to go direct to the LNB, nothing between the antenna (Dish) and the receiver save for perhaps a connector or six, and of course RG-6 coax, a ground block counts as a "Connector or two)
OPTIONALLY, if you have a dome antenna on your roof, you can use a simple antenna switch (NOTHING ELECTRONIC, just a less than 10 buck switch from Aco hardware or it's equal) to select the antenna (A)bove (Dome) or (B)elow (Ground mounted dish up to 100 feet from rig and not blocked by the famous signal eating tree) If you don't have a roof top antenna, you don't need this.

I may be a little late to the party, but I am confused after reading these threads. I want to hook one converter so that I can keep my VCR, 2 TV's working through my selector box. I want to be able to play vcr tapes. I also assume after Feb. 09 I will not be able to record on my vcr. I have learned that there is 12 volts going to the batwing antenna and this could be a problem if not connected correctly. I think I could hook the converter to the aux. that is not used, but am not sure how this would be wired or connected. Will it operate both tv's and not interfere with the 12 volt antenna booster? I don't care if I have to watch the same channel on both tv's but it would be nice if I could watch them on different channels.
Yep, I am confused so any help will be appreciated.

You have a couple of different things that are all related here so I'm going to make some comments on what you have said and if you have more questions please feel free to ask!
First off, your VCR probably has an analog tuner like most older TVs so yes, it probably won't be able to record off-air programing. It will still playback your existing tapes just fine.
Quote: I have learned that there is 12 volts going to the batwing antenna and this could be a problem if not connected correctly.
This is true. The standard Sensar batwing antennas have a preamplifier built into the head of the antenna (I should say most do, there are some that don't). A typical installation for the antenna involves a wallplate located someplace in the rig with an LED and a switch on it. That wallplate injects 12v onto the coax going up to the antenna head to provide power to it's built-in preamp. You do NOT want to install your DTV converter between those two.
There are also some Winegard switch boxes that provide the 12v power instead of a wallplate. If that is the type of setup you have then you don't want to install between the antenna and the switchbox input either.
Quote:I think I could hook the converter to the aux. that is not used, but am not sure how this would be wired or connected. Will it operate both tv's and not interfere with the 12 volt antenna booster?
If you have the wallplate setup you should be able to disconnect the "Antenna In" from the switchbox and connect it to the "Antenna" connector on the DTV converter. Then you'd just need a short cable to run from the DTV converter "Out" to the "Antenna In" connector on your switchbox.
If you have the Wingard switchbox providing the 12v to your antenna then that configuration won't work. Please let me know if you do have this and I'll work out an alternate solution for you.
Quote:I don't care if I have to watch the same channel on both tv's but it would be nice if I could watch them on different channels.
With only a single DTV converter you'd be limited to all TVs watching the same channel at the same time. To be able to watch more than one channel at the same time you have to have another DTV converter. The ideal situation would be to install a DTV converter at the TV and VCR output jacks on your switch box. That would allow you to watch/record different channels on each.

This makes it very easy.. You have 2 choices, I have implemented one and when I find the hardware (It's somewhere in the MH) I will implement the other.
IF: the unit has analog pass through put in in the VCR LOOP ahead of the vcr and then you can record it's output or after the VCR IF IT HAS ANALOG pass through (Even if the analog pass through is poor it should pass the VCR output fairly well)
If it does not have analog pass through E_mail for a JPG of how to work around that
Option two (Which is explained in text in the JPG by the way) is to do this...
Optain a "Diplexer" From radio shack (Just go to www.radioshack.com and search on it) or just Go Here to see one
This unit has 3 connections, As pictured the one on top is the "Common"
Disconnect the lead connected to the FROM ANT (or ANT or ANTENNA) on the back of the distribution switch and hook it to the COMMON on the diplexer, hook a short jumper from the POWER PASS THROUGH port (The bottom right as pictured) to the FROM ANT port on the switch box
Connect the other port (Bottom right as pictured) to the converter input
Connect the converter OUTPUT to the AUX IN port on the switch box
That works with or without analog pass through
NOTE: Thanks to another forum member who figured that one out.
