Before installing, please note the following important factors in determining your zBoost
performance:
• At least 15 vertical feet is needed between the External Antennas (receives the outside signal)
and the Indoor Antenna (rebroadcasts the signal indoors). Separation less than 15 vertical
feet will result in decreased performance. See illustration below.
• Keep the External Antenna at least 3 feet above any metal.
See “Installing Your zBoost Signal Booster” on page 5, for additional information.
Cable Requirements
RG-6 cable is used to connect the External Antenna and the Base Unit. Should you need additional
cable length, 15 foot extensions (Part #:
YX030-15w
) are available at www.zBoost.com.
The total cable length should not exceed 65 feet unless you also purchase an upgraded External
Antenna or upgrade the cable to RG-11. (see page v). The recommended maximum length
for RG-11 is 120 ft. A longer cable is helpful only if it allows you to place the External Antennas
in a location where you measure stronger signal. It is highly recommended that you refrain from
securing your cable, drilling any holes, etc. until you complete and test the installation of the
system.
Caution: Before drilling any holes into a wall to run your cable, make sure you know where existing
electrical wiring is located. Drilling into live electrical wiring could cause an electrical shock and
sever the wire.
Grounding the Directional External Antennas
If you decide to place the External Antennas outdoors, it must be properly grounded. (See page
v for a recommended grounding kit).
The set up must be in accordance with Article 810 of the
National Electric Code (NEC). A listed antenna discharge
unit must be provided for the lead-in coaxial cable per NEC
article 8.10.20 or the shield of the coaxial cable must be
permanently and effectively grounded in accordance with
NEC article 8.10.21. Please consult a professional installer
or electrician for more information.
Securing Cable with a Drip Loop
When you install the Directional External Antennas, create
a drip loop with the coaxial cable at the point where the
cable enters the home through an outside wall. This can be
done by twisting and securing the cable into a loop (no less
than 4” across) near the entry point. This will help prevent
moisture from gathering at entry point and leaking into the
home.
