Yagi antenna matching

[W4PJB]

I'm building a handheld 2-band satellite antenna (similar to the Arrow), and debating on which is the best way to match the impedance.

Design requirements for the antenna are light weight, maximum portability, and minimum setup. That leave a Gamma match out, as I don't want to have a bulky parallel element to disassemble and pack. The beam will be non-conductive (C/F and 3D printed components), and will use a split driver on both bands. Most likely I will be using 7.2mm arrow shafts that screw into permanently mounted nuts on the beam. This means the wiring and matching circuit can stay attached to the beam, and I just need to screw on the elements when assembling. Beam will be two pieces.

So for the matching, I think that just leaves a hairpin or parallel match using 75ohm coax (DK7ZB style).  Pros/cons over each? Am I missing any other options?

Pic attached for reference. Next step will be designing the element mounts (and matching will be part of this design). There is also a removable phone mount, so I can track satellites using Stellarium.

Well.. vhf / uhf cross yagi?
What kind of dipole you have planned to use?

[W4PJB]

Thanks for your reply. It will be a UHF/VHF cross Yagi, like the Arrow.

For the dipoles, I intend to use a split dipole, rather than a solid element.

Have you antenna analyzer?.
I think you chould use vhf for horizontal and connect uhf dipole elements vertical for same feed points.

The hairpin worked great on some 2m tape measure yagi's I made for fox hunts.

I also have an Arrow for satellite work - but the weight is a real issue. Will be watching this thread for progress updates.
