Isotron antenna for 80m band
For the 80 m band the coil is wound with black 1.5 mm installation wire of approximately 10 m length. The antenna resonates at 3,630 MHz with a bandwidth of + and - 22 kHz

Broadbanding half square antenna for 80mt
Half-square antenna is by naturerelatively narrow band.1On80 meters, for example, an SWR be-low 2:1 can be achieved anywhere in theband, but only over a relatively small range 60 to 100 kHz
Double bazooka/coaxial dipole antenna
A typical, dipole antenna has bandwidth of about 50 to 100 KHz
Hex Array 80/40 Meter Vertical
Homebrew 80/40 meter trap vertical. The trap is a coaxial cable trap, made from RG-213 cable
