Combing two hf Antenna? Do I need coupler or multiplyer/mixture or splitter?

[patelkes]

Hi Everyone,

I wants to combine two HF Antenna. One is capturing verical oriented hf waves and another is capturing horizontaly oriented waves.(both from 1 mhz to 30 mhz)

I wants to combine in a way that there is a sum of both amplitude in a 0 degree phase manner.

Can any one help me to select right method and device?

Thank you.

A hybrid splitter/combiner something like this one should work for you

Consider that combining two antennas with orthogonal polarisation will simple produce a 45° polarized antenna characteristic. You can achieve the same by using one 45 ° rotated antenna.

I have one Antenna which is discone antenna which capture verical hf signal. Another antenna is bushcraft 3 line EFHW which captures horizontal hf (NVIS)

Both has a hf signals. Some time discone is good some time bushcraft EFHW is good. That is the reason I wants to combine both...

I understand the motivation. But both antenna signals interfer and don't necessarily add to higher magnitude.
