Canadian Tower Corporation has the PEOPLE, the EQUIPMENT, and the EXPERIENCE to complete the tests required for compliance with Health Canada’s Safety Code 6. The engineer-stamped report is required to ensure safety to the general public from possible over-exposure to Radio Frequency energy.
Tower Inspections: All towers should be inspected on a regular basis, typically annually depending on location. Canadian Tower Corporation can complete tower inspections both brief and thorough. A typical tower inspection will include:
- A complete inventory of antennas and cable
- Inspection of paint and lighting
- Check all structural fasteners
- Verify tower alignment using a transit
- Check anchors and anchor rods
- Check anchor rods for possible corrosion 1’ below the surface
- Verify guy cable tension
- Verify grounding strategy
All to be completed in a report with a tower diagram, photos, wind loading calculations against CSA S37-01 standards with a Professional Engineer stamp.
Tower Colocation
We own numerous towers of various sizes across Manitoba. If you require
tower space for you antennas for 2-way radios or wireless gear, call us
today.
Rooftop Management / Site Management
We are able to manage your building rooftop's income potential by
working with companies needing to acquire key antenna locations, and
matching them up with the most ideal rooftop locations. We also
will help coordinate a third party install as well. We can manage
antenna installations, cable runs, and rack space for rooftop
installations, freeing your maintenance staff from the task of
overseeing this sometimes highly-technical responsibility.
Health Canada Safety Code 6 Compliance Testing
Safety Code 6 (SC6) is a set of specifications developed by Health
Canada and enforced by Industry Canada to define limits for the safe
exposure of humans to radio frequency emissions from all emissions from
all antenna systems at any given site.
SC6 certification of a site is conducted by professional radio engineers
using either a "calculated" or "measured" approach. Pros and cons exist
for both approaches.
For the calculated approach, Industry Canada published procedures and
how to calculate near field effect of parabolic antennas but recommends
that for dipole arrays and whip antennas near field effects be measured.
For tower installations, RF hazards for the general public occur in the
far field of the antenna apertures and the calculated approach is the
simplest means to determine SC6 limits. In fact, testing exposures along
the tower length is often not possible due to strict Workers
Compensation rules limiting engineers from climbing towers unless they
have special tower climbing certifications and insurance. Because of the
difficulty to certify towers along the tower length, many tower riggers
are equipped with personal RF safety meters which flag to the rigger
those hot spots on the tower where hazards exist.
The biggest challenge with the calculated approach is the collection of
accurate data. In sites shared with other RF operators, a list is
developed of all other tenants and their antenna systems, output powers
and frequencies. And even with this listing of information, there is always
concern over accuracy as operators tend not to keep their as-built data
current with their licensed data. For the many unlicensed systems
prevalent at shared radio sites, data collection is exceedingly
difficult as it involves contacting each unlicensed operator and asking
for the information. For the measured approach, Engineers use Industry
Canada recognized test equipment and conducts site walks. This approach
is the most practical and economical for roof top sites.
