Pre-Deployment Checklist
[ ] The mounting hardware fits the diameter of the
tower leg.
[ ] The Grounding Ring is installed properly
according to the table.
[ ] All components are securely connected..
[ ] The feed cable rated capacity is not exceeded and
is correctly paired to the rating of the Antenna.
[ ] Electrical tape is used at the connection point
between the feed pigtail (antenna feed lead-in)
and the feed-line connector.
[ ] If a feed cable adapter is required, the gender is
correct.
[ ] Inspect the element’s feed pigtail (antenna feed
lead-in) for connector damage, cable kinks,
or pinching. Do not install if damaged; call
Electronics Research Inc for assistance.
Attention Installer
Do not install the Antenna near other tower
1.
mounted Antennas. Always mount the Antenna’s
Boom pointing in the direction of desired
coverage.
Always mount the antenna with the Strap
2.
Insulator pointing up.
Ensure the feed pigtail stays coiled until you
3.
reach the tower location to mount the antenna.
If a 2-Bay* configuration is being installed,
4.
mount the elements directly above one another
using the bay spacing distance furnished in the
Bay Spacing table.
Always tie down loose cable to the tower using
5.
quality tie-down material.
The length of certain horizontal and diagonal
6.
tower members can create resonant conditions
that may impact antenna VSWR performance.
If possible, avoid 30” to 60” dimensions
corresponding to ¼ and ½ wavelengths.
* PD100A power divider and second 100A element is
required for the 2-Bay arrangement. The Power Divider
is secured to the tower using stainless steel hose clamps
furnished with the Power Divider. Seal power divider
connections with electrical tape.
