Re: Connecting Digital Converter Box to an old TV

Why not just take off the 4" pece, and connect the cable right to the

Wait! I do know! Because it's a shy too short to reach my box when
placed on top of my TV set?

Ok, I get this. Looks easy now. I got caught up in the other
connections on the back of my TV, and the idea that it had to be
harder because I am not an enguneer. :)

But, let's see if really get it... how about this... the way my TV is
configured now, those two wires that come out of the TV case, on the
left, aren't they simply the leads from my twin telescoping antennae?
And having them connected as they are to the VHF screw-down inputs
simply connects them to a built-in balun inside the TV whose output
appears as the female "75 ohm out" connector? And that is why the
4"cable had to connect to it, to finally connect the antennae to the
VHF tuner?

If yes to all of that, then this cross-connect panel on the back of my
TV is just a typically inelegant way of going out and in and out and
in, allowing a choice of connecting to my VHF tuner by either external
coax cable TV or my internal telescoping antennae? Why I ever got
confused... well, that's me, expecting, uh, elegance. It is elegant,
though, for what it is.

yeah, it is a bit ugly like that.

Question: Since my coax tuner input says "VHF", then what tuner do my
UHF screw-downs connect my bowtie to? A UHF tuner inside my TV,
perhaps? And, unlike my VHF tuner, this UHF tuner has no option to
access it via coax?

yes, the UHF screws go straight to the UHF tuner inside the TV.
if you want use coax for uhf you need to use a balun.

the TV has separate UHF and VHF tuner... if you want to use the
passthrough feature of the converter to use the UHF antenna for analog
tv the output of the converter needs to be connected to the UHF input

My converter box came with a male-male coax jumper. Yeah, I'll need a
bullet.

Also, will need a balun for my bowtie. Sounds like a song. ;)

If the converter box outputs UHF then you'll need to use a balun and
hook it to the UHF input, if it outputs VHF you can hook it to
the coax cable (using a bullet coupler)

if it's outputting VHF the passthrough feature won't be much use.
