1. Scope
All small cell antenna installations must meet, at a minimum, the current applicable NESC
standards, FCC, and FAA rules and regulations. The administrative authority may have additional
requirements depending on the location of the installation. This guideline is intended to:
l Provide guidance on install locations on a distribution pole according to Federal Com-
munications Commission (FCC) 11-50 and 47 U.S.C. (United States Code) 224
l Provide assistance to company personnel in evaluating correct installation of tele-
communications equipment to avoid system operation problems
l Supplement published company distribution construction standards, policies, and procedures
l Implement common minimum practices throughout the company's service territory that comply
with applicable codes, ordinances, and tariffs
2. Changes or Conflicts in Requirements
Where city, county, state, regulatory agency, or other administrative authority requirements
exceed the company’s requirements, the more stringent requirements shall apply.
Exceptions to the requirements shall not be permitted except when physical restrictions make
compliance impractical, when required by an administrative authority, or where all parties involved
are in agreement.
Depending on the local operating and weather conditions, deviations from this guideline may be
required as determined by local engineering and operations. It is incumbent on those performing
the design and site work to fully understand the requirements necessary to complete the
installation safely and in compliance with federal, state, and local regulations.

BHE DSG-JU-01—Small Cell Antenna Installation Guidelines
Small Cell:Types of small cells include femtocells, picocells and microcells – broadly increasing in
size from femtocells (the smallest) to microcells (the largest). Any or all of these small cells can be
based on ‘femtocell technology’ – i.e. the collection of standards, software, open interfaces, chips,
and know-how that have powered the growth of femtocells.'Small cell' is an umbrella term for oper-
ator-controlled, low-powered radio access nodes, including those that operate in licensed spec-
trum and unlicensed carrier-grade Wi-Fi. Small cells typically have a range from 10 meters to
several hundred meters.
Note:This definition of small cell is derived from the Small Cell Forum,
http://www.smallcellforum.org/.
3.2. Acronyms
FAA:Federal Aviation Administration
FCC:Federal Communications Commission
NEC:National Electrical Code
NESC:National Electrical Safety Code
OSHA:Occupational Safety and Health Administration
4. Coordination Between the Company and the Telecommunications Company
Close coordination will be necessary with the telecommunications company to complete the
installation. In addition, company personnel use terminology unfamiliar to the communications
industry; be aware of the resulting gap in understanding. This guideline may be shared with the
telecommunications company prior to designing the installation so that the telecommunications
company may be aware of the company’s basic requirements.
5. Supplemental Information
This guideline is not considered all-inclusive. The company may have additional installation
requirements. In addition, the administrative authority responsible for approving specific
installations may have additional requirements not covered by this guideline.
The company’s joint use department may provide assistance with the application process.
6. Pole Selection Criteria
Installation of communications equipment is limited to poles carrying electrical distribution facilities
only with voltage level of 34.5 kV and below. The selected distribution pole is not encumbered by
electrical equipment that includes, but is not limited to, an air break switch, transformers, capacitor
banks, regulators, reclosers, down guys, or risers. Installation of communication equipment on
distribution poles are at the sole discretion of the company. The priority of selection of appropriate
pole candidates for small cell antenna attachments is as follows (in order of preference):

7. General Installation Requirements
The following covers the basic installation requirements for small cell antenna attachments. This
list may not include all requirements needed for installation:
l Only one antenna array attachment installed per pole.
l Installation is on a “clean” pole. The pole is not encumbered by an air break switch, trans-
formers, capacitor banks, regulators, reclosers, down guys, risers, or other electrical
equipment.
l Distribution facilities are nearby for providing electrical service.
l All work is performed by an authorized qualified worker if the installation is in the supply space.
l Power outages needed for equipment installation must be coordinated with the company.
l Zoning, clearance, building permit, easements, and other required permits or approvals by the
administrative authority are obtained by the telecommunications company.
l The company retains the right to remove the antenna equipment if requested by the admin-
istrative authority.
l The telecommunications company shall perform a TOWAIR (or Landing Slope Facility Cal-
culator) study. The study shall be provided to the company to be filed with the FAA. If the FAA
requires the structure to be registered, an Antenna Structure Registration number must be
obtained from the FCC. The telecommunications company is responsible for all
FAA requirements.
l The telecommunications company shall provide estimated electrical load information of the
installation to the company.
l Antenna array wind loading information is provided to the company. A separate pole loading
calculation study may be required to be submitted by the telecommunications company.
l A lockable disconnect switch capable of de-energizing the antenna system and metering
equipment shall be provided and installed by the telecommunications company. The dis-
connect switch shall be located on the pad-mounted pedestal, if a pedestal is used; otherwise
it shall be located in the pole-mounted enclosure. The disconnect switch shall be designed so
the open position can be visually verified. Breakers or other non-visible disconnects are unac-
ceptable.
l The telecommunications company must notify the surrounding residents and landowners
when the pole modifications will be made.
l The telecommunications equipment owner shall incur the cost of removing the equipment from
a pole in the event that the equipment is abandoned.
l The telecommunications company must notify the company at least 45 days in advance when
an outage will be required to service an installed antenna.

9. Additional Equipment Requirements
9.1. Communication Equipment Requirements
Supporting equipment for antenna operation may be installed on the pole at the company’s
discretion. The size of individual antenna array volumes shall not exceed three (3) cubic feet.
Supporting equipment shall not exceed a combined volume of 11 cubic feet and a combined
weight of 250 lbs. and must be a minimum of eight (8) feet above the ground to the bottom of
the cabinet.
The company, at its discretion, may allow the supporting equipment to exceed these weight
limits based on a PE-stamped design and pole-loading calculations demonstrating that the
proposed installation will not adversely affect the existing facilities. Equipment not meeting this
criteria or not approved by the company must be installed in a pad-mounted communication
pedestal (see Figure 5). To ensure access to the pole is not blocked, the company shall
specify the distance between the pad-mounted communication pedestal and the pole.
Conduits shall be run underground between the pole and the pedestal.
A disconnect switch capable of de-energizing the antenna system and metering equipment for
the electrical service (if applicable) shall be housed in the pad-mounted communication
pedestal, if one is used.
9.2. Grounding
The telecommunications company must install their own NEC-approved ground and bond it to
the company’s ground. If a ground is not available on the pole, the telecommunications
company must request the company install a ground.
The telecommunications company is responsible for providing adequate lightning and
over/under voltage protection to protect their antenna system from damage due to system
voltage variations.
10. Climbability
10.1. Climbing Space
All communications equipment on the distribution pole must be installed in a manner that
maintains climbing space according to the NESC. The antenna installation must not impede
the climbing space on the pole.
10.2. Bracket
Standoff brackets must provide at least 4.5 inches of clear space from the surface of the pole.
The company prefers all additional antenna equipment be installed in the communication
pedestal. If it is necessary to install an additional communications equipment cabinet on the
pole, it must be mounted on the pole using a standoff bracket if the height of the equipment is
over 12 inches. The allowable size of the cabinet will be limited based on its total wind loading.
Any communications equipment exceeding the maximum wind loading of the pole shall be

installed in the communication pedestal. Only one communications equipment cabinet may be
installed on the pole.
10.3. Conduit
All conduits on the pole must not interfere with a lineman’s ability to safely climb the pole.
Conduits less than two inches in diameter may be banded to the pole. Conduits must be
mounted on standoff brackets in instances where a conduit is larger than two inches in
diameter, or where there are more than two conduits.
Where a single-phase primary dip is already on the pole, the communications conduit
standoffs shall be mounted jointly with the company.
All communications conduit entering the supply space must be non-conductive per NESC. All
metallic conduit outside of the utility space installed on a pole must be bonded to the pole
ground.
10.4. Steel Poles
If a steel pole is used for an antenna attachment, communication cables need to be routed
inside the steel pole. There may be additional requirements specified by the company for this
pole configuration.
11. Radio Frequency
The telecommunications company shall affix a sign near the base of the pole reading “High
Energy Field – RF Monitors Must Be Worn.” If the disconnect switch is installed on the pole, this
sign shall be affixed near the disconnect switch equipment box.
The installation must be in compliance with the FCC Office of Engineering and Technology
(OET) Bulletin 65, "Evaluating Compliance with FCC Guidelines for Human Exposure to
Radiofrequency Electromagnetic Fields."
