The mighty wide six metre dipole
Simple 50 ohm coaxial feed design, no Antenna Tuning Unit required, Wide Bandwidth - 50 . 00 to 52 . 00 Megahertz
The X-antenna antenna for portable work on 6m
The 4 rods go through holes grommet sealed in a small round plastic box. The rods I used have 10 sections with a maximum diameter at the base of 9.5mm. When un-extended they are 16.5cm in length and 131cm when extended
