3. Assemble the 2.75" OD element tube to the 3" OD element tube (installed on the Extren
®
insulated channel) using the two stainless steel 3-1/2" long 1/4" bolts, four stainless steel flat
washers and two 1/4" stainless steel Nyloc nuts as shown below. When tightening the bolt and
Nyloc nut, tighten them enough to hold, but not tight enough to deform the aluminum elements.
DANGER: When raising or lowering the vertical antenna make sure you have
not inadvertently located the antenna underneath or near power lines.
Residential power lines are often less than 40' high.
Contact with any power or utility lines Can Be Lethal !
In areas where there is a high atmospheric static condition (areas prone to precipitation or snow
static) this antenna (as with all antennas) will build up a static charge. When working on the
antenna, especially in the raised position, you may want to ground the antenna to bleed off any
static before touching the antenna. (Obviously, you also do not want RF present on the antenna
when touching it). When installed, the base series and shut coils (described below) will also act as a
constant static bleed for your vertical antenna in areas where precipitation static or snow static is
present.
When the vertical elements are all connected together, the overall total length measured from the
bottom of the 3” OD base element to the top of the capacity hat assembly will be approximately 55
feet in length.
