Helix antenna design and construction details
Design frequency MHz, Number of turns ,Turn spacing, wavelengths

Inductance of a Straight Wire, One End Grounded
Any length of wire has some inductance, however, at low frequencies, 1-30 MHz, the added effect of this inductance is usually minimum

J-Pole Antenna Calculator
If the antenna is to be placed outside, do not use brass, photo model designed for 2.45 GHz. A capacitor of 0.8 pF and it would be perfectly matched to 50ohm
