Hello, Thank you for the great info on combining two antennas.

As a four year hobbist, you all gave me some great information.

Some of your advanced info will take me quite awhile to try to get my head around & understand it. I am definitely Not the sharpest pencil in the pencilbox.



Question

1. At most peoples homes,in their junkdraw if it contains a splitter, will it 99 % of the time be a passive splitter?



2. Both directions?



3. By looking it, how can we tell?



Here is where my dumbness really shows. (Please don't belittle my IQ. When I was a child, nobody told me not to eat lead paint)



You had mentioned "DC CURRENT".

4. Does "DC CURRENT" occupy the entire Master Antenna System?

Or only in certain locations?



(Master Antenna System - From antenna thru connectors,thru cables,

thru preamp, thru cable, thru in-house amplifier, thru

splitters, thru cables, thru analog/digital converter box, thru

cables, to the tv set.)



Thank you "jhtaylor2001" for teaching how to fabricate a splitter.

You did a very good job at explaining how to do it. It will take a long time for this newbie to get a grasp of it.



As my antenna hobby evolves I might figure out the concept of a

"arc axis antenna" in the consumer world. Maybe something Convex.

5. Could a circular antenna like the Winegard MS 1000 or Channel

Master CM 3000A Omnidirectional TV Antennas be "arc axis" ?

6. Or does a convex magnification need to be in a "arc axis" theory?



I think that previously in analog broadcasting, if a person used a powerful antenna too close to the broadcasting tower, they would get signal overload. Example: Using a Channel Master 3671 one mile from broadcasting tower.(No reason for it, just an example).



7. In digital broadcasting, can there be signal overload if we use a

to powerful antenna?



Thank you for your contribution to my hobby.

No. I'd say 30/70 blocking/passive.



2. Both directions?



Yes. Be it blocking or passive, it will be in both directions. Some will be

passive in one leg and blocking in the other.

Some splitters will have a "|" or "/" on a DC passive leg. Most have no

passive/blocking labeling. Some will say "All port DC passing" on the label

of DC passive splitters. Some won't.

Most don't. A DC ohmmeter perhaps?

Yes, a multimeter will tell the tale, and, better to test something than to guess.
