Thanks Dave, by antenna coupler I meant a power combiner, but,
precisely, since channels which are emitted from tv transmitters
(obviously in 2 directions from my home) are not overlapping, nor are
adjacent, I think
of pointing logperiodical antennas to transmitters and couple them into
one tv cable towards receiver.

Use a phasing harness or an antenna coupler.

You COULD build a coupler with a few inductors and capacitors, but... why
bother? A good quality vhf/vhf combiner (aka splitter) or uhf/vhf combiner
(aka duplexer) is about $5 US.
