Dropping TV channels
Here is a frustrating one. Have 2 TVs. Over the air only. No satellite. Yes set for over the air at the ant/cable button. We have a Jack ant. Upon arriving in a new area each TV, 2 of them, is scan...

I sort of get what you are both saying, brother was avid HAM. I have 3 TV connections, bedroom, living, basement. That mean I have two splitters? I know where to find one. Then how do you know it's a good splitter vs cheap? Last is there a way to test them? That's my project in the next few days.
You can buy 2 way, 3 way, 4 way or more passive splitters.
You can "nest" splitters.. In other words take a two way then on one output put another 2 way.
The problem however is each time the signal is split you get massive losses (three DB is like cutting your signal in half so 3.5 DB is even a bit worse than half..
Two way splitters are 3.5 DB loss.
Nesting a pair of 2way gives you one port with 3.5 DB loss and two ports of 7 DB loss.
Three way splitters basically are the same as nesting two 2 way splitters with one port with 3.5 DB loss and two ports with 7 DB loss.
Simply put, in the digital age passive splitters will kill your signal enough that the RF noise surrounding your trailer can easily drown out the channels.
The base of ALL passive splitters is nothing more than 75 ohm 1/8 watt resistors.. Yep $.05 cent resistors, so whether you buy $1 splitter or a $100 splitter the heart of it is nothing more than $.05 resistors.
They are completely passive with no other electronic devices inside.
Sure, you could buy gold plated ones but in reality it won't fix the 3.5 DB loss of the resistors.
You don't NEED to buy expensive splitters, anything more than $2.00 is wasting money no matter what some of the supposed smart folks on this forum say (perhaps I can make them a deal on a certain bridge in New York?).
