Based on formulas given in the ARRL Handbook

Dipolo grosso 435 MHz, 50 ohms
Antenna is the coaxial version of the J antenna J pole, see here. It consists of a radiating element of half wavelength

FM Dipole for 88-108 MHz 50 ohm
Si inspira al progetto sperimentale dello ZED Dipole per la banda amatoriale VHF

Folded Dipoles for VHF/UHF Yagis
How do I make my own VHF/UHF folded dipoles from aluminium tubing ?
