SteppIR BigIR Vertical Antenna Assembly & Installation


SteppIR BigIR Vertical Antenna Assembly & Installation

The BigIR Vertical omnidirectional coverage on all of the HF bands from 80m – 6m and is a good DX antenna due to a vertical antenna's characteristic low-takeoff angles

A Modified Petlowany Antenna
It is essentially a very short dipole with spiral-wound coils at each end

Antena vertical
Outside of the wave traps there is nothing difficult in the construction of this antenna; the traps are of homemade construction and we will use a simple ingenuity to make them

Vertikal Dipole 10-40m
The modelled inverted-V antenna is full size and will have a higher efficiency than a shortened horizontal dipole. If we consider a full size 1/4 wavelength

50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
