Optional: DXE-RADP-3 Radial Plate, DXE-FDFB-KIT SecureMount™ Bulkhead Connector
and DXE-FP-WIRE-P Feedpoint Wire and Connector Assembly
The optional SecureMount™
DXE-FDFB-KIT
is a hi-quality bulkhead connector with silver
plated outer and inner conductors and PTFE insulation. The connector has
very low loss and high electrical break down. It comes with the hardware to
secure it to the DX Engineering Radial Plate and ensures the radial ground
system, antenna ground and the feedline shield are common. The optional
DXE-FP-WIRE-P
Feedpoint Wire Connector Assembly is a perfect
solution to connect the feedline to the vertical element. Don't forget to
weatherproof the PL-259 coaxial connections.
At a minimum, 30 radials, each 1/4-wavelength long on the array frequency should be used. Arrays
using 40 to 60 radials are preferred and highly recommended. If you have very rocky or mostly
sandy soil, using more longer radials may help the performance of your phased antenna system.
Extra radials help overcome unknown poor-soil conditions, improve efficiency, and ensure the best
performance.
DXE-RADW
Radial Wire, a stranded 14 gauge PVC insulated copper wire is
suggested for the best results.
The 1/4-wavelength wire radials should
placed as symmetrically as possible straight
from the feedpoint around each of the vertical
antennas that are spaced 1/-4 wavelength
apart and spaced evenly, regardless of how
many radials are used. Where the radial wires
from one antenna cross the radials of the
other antenna, cut the wires and bond them to
a common wire or copper strap as shown. If
you have limited space, put in as many
straight radials as you can. The radials must
be connected to the shield of the respective
feedlines.
DXE-RADP-3
Stainless Steel
Radial Plates are the ideal optional items
which provide an excellent system for
attaching radial wires to your vertical antenna
system feedpoints.
