Re: 27MHz Antenna

I think that actually you are looking to build a Whip antenna, loaded with an inductor.
Helix for 27MHz is a giant antenna (doesn’t matter for what mode, normal or axial), and probably to get the right load impedance you need a ground bigger than your car.
Helix is dedicated mostly for UHF and SHF frequencies.
