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.
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.
