Introduction
The DX Engineering
40/30 Meter Vertical Antenna is a high performance 40/30 meter vertical
dual-band antenna that is tunable to operate with an SWR of 1.5:1 or less. Designed with 6063
corrosion-resistant aluminum tubing and stainless steel hardware, this antenna is very durable, free
standing, attractive, and is an optimized height of less than 30 feet.
Of course, another key to performance is a good ground radial system. 32 radials, 32 feet long are
recommended. Fewer radials will work, but with diminished results.
The
40/30 Meter Vertical Antenna includes the antenna element, insulated mounting channel,
mounting plate, patented Tilt Base, stainless steel hardware, and stainless steel element clamps.
Features

Full band coverage on 40 and 30 meters with SWR under 1.5:1 No Tuner needed

Bandwidth greater than 750 kHz with SWR under 2:1

Tunable above and below 7 MHz range for MARS and CAP frequencies

Power Handling up to 5 kW

Less than 30 ft overall height

Self Supporting Vertical Antenna

Heavy Duty design to withstand 60 MPH wind without guying
Supplied Installation Items:
DX Engineering’s patented Tilt Base - Precision laser cut from 3/16 inch thick 304 Stainless Steel,
this mounting plate is virtually indestructible. Using the included two DXE-SSVC-2P V-Clamps,
the Tilt Base is mounted to the same mast that you use for the optional radial plate. The Tilt Base
Allows for easy installation, tuning or severe weather lay-down.
Additional Material Needed but not Supplied:

Antenna Mounting - Steel mounting pipe, up to 2.0
″
OD, 0.25
″
wall thickness. The
standard 1-1/2" galvanized water pipe (with its 1.9" OD) is just fine for this application and
can usually be found at your local home building supply store.

Quik-Set Concrete - Mounting pipe installation (depending on your landscape material)

JTL-12555 Jet-Lube
™
SS-30 Pure Copper Anti-Seize - To ensure good connection for
aluminum element sections. Also used on the threads of Stainless Steel Hardware to prevent
galling and aid in proper tightening torque
