Tv Reception.
The VHF low band digital channels 2 thru 6 are more negative effected by natural earth electric noise and human made electric and electronic noise/signals.
Having a antenna in the attic reduces signal strength and like the inside of a house , attics have human made electric and electronic noise.
It is best to have a antenna that has the long metal receiving elements for receiving channels 2 thru 6 to receive more of the desired Tv channels to over come electric and electronic noise.

The popular buzz words are , Pull In , Tv signals.
Tv antennas Do Not in any way shape or form "pull in" Tv signals.
Tv antennas Receive Tv signals that arrive at the metal reception elements.
The more metal reception elements and the more lengths of the the metal reception elements that resonate with the frequencies/Tv channels the better the reception will be.
The metal reception elements for Tv channels 2 thru 6 are long metal reception elements.

Combining tv antennas as you are suggesting with baluns and reversed splitters will produce negative results because of antenna cross talk and loss of reception strength because the strength of signal of one antenna is transfered to the other antenna and the antennas will be out of phase and the result is more signal loss.
There are combiners that have tuned circuits that combine UHF and VHF , UVSJ = UHF/VHF/Separator/Joiner.
And VHF low band 2 thru 6 and VHF high band 7 thru 13 , HLSJ = High/Low/Separator/Joiner.

For this question askers reception situation , there is no requirement to jump through hoop after hoop , install one antenna and be done with it.
I have been doing antennas for a very long time , I do my best to recommend reception with the least amount of hoop jumping.
