OPERATING MANUAL
D130J/D130NJ Super Discone Antenna for Wideband Reception
The D130J/D130NJ Super Discone Antenna is
the first ultra-wideband antenna in the market
which can cover amateur radio, air traffic
control and other various utility frequency
bands and, in addition, even some amateur
radio frequency bands within the covering
frequency range can be transmitted with this
antenna
alone.
The
D130J/D130NJ
designed to be able to assemble very easily
and can be built in a couple of hours by
beginners.
Rust
free
stainless
employed in major component parts to have
the antenna rust resistant and durable. And its
very compact and lightweight design enables it
to be installed at any convenient place.
Description
1. Ultra-wideband design to be able to cover
25-1300MHz.
2. Very compact and lightweight design
enables the antenna to be installed on
balcony railing at an apartment or
condominium.
3. 6m, 2m 70cm and 23cm amateur
frequency bands and 33cm band
(900MHz) can be transmitted.
4. Since all radial rods are designed to have
the same length, the D130J/D130NJ is
perfectly omnidirectional as original
discone antenna and can receive radio
propagation from any direction evenly.
5. The D130J/D130NJ can be made further
compact and lightweight by removing the
top element assembly, if it doesn't require
to receive lower end frequency range.
