MINIMUM EXPOSURE LIMITS AND PRECAUTIONS
When personnel are aloft, the RCN recommends a minimum distance to be maintained from sources of radio emissions. This is referred to as Minimum Exposure Level (MEL) and is measured in meters. These are the numbers for the Kingston Class vessels:
VHF MEL =1 m
INMARSAT MEL = 2 m
M SAT MEL = 1 m
Mini-M MEL = 1 m
Telular MEL = 0.5 m
Marine Mobile VHF MEL = 1 mFor HF whip antennas:
Greater than 600W: After 4 m of the bridge top is denied access.
100W to 600W: After 2 m of the bridge top is denied access.
Less than 100W: Bridge top is unrestricted
Key Returned or Positive Control EvokedUHF: Key Returned or Positive Control Evoked
S Band navigation radar: Key returned or positive control evoked. MEL =1 m
X Band radar: Key returned or positive control evoked.General: Personnel shall not come in contact with long thin vertical conductors (e.g. crane hook or wire, vertical RAS cables, etc.) when HF is in use.
The MEL is in accordance with Health Canada's Limits of Human Exposure to Radio Frequency Electromagnetic Fields in the Frequency Range from 3kHz to 300GHz, Safety Code 6. This establishes the power levels which are hazardous to humans in each frequency range. The measurements for each antenna's MEL distance are done in accordance with Industry Canada's GL-01 document.

| Photo # Radio Ant 7 . Starting in 2006, Sea Tel Maritime VSAT Tx/Rx antennas were installed on the Kingston class vessels. Operating in the Ku Band, the antenna is capable of providing asymmetrical Internet connectivity to the ship using 1024 bps for shore-to-vessel communications (download) and 256 kbps for vessel-to-shore communications (upload). Also available aboard, is satellite TV for the crew. Bell Express Vu is the provider. Two ships in the Kingston class have the Global Star Satellite phone system as of March 2007. The mini-M satellite phone system is used by crew to dial home. They are sometimes referred to as Quality of Life phones because they help to provide a better quality of life aboard ship.

# Radio Ant 9 . The WaveCall 4006 is a 1-meter Ku-Band maritime VSAT
antenna whose efficiency is better than 70% across the transmit and receive
bands and is ideal for vessels that require "always-on" broadband satellite
communications. The 4006 is suitable for file and image transfer, video
conferencing, e-mail, Virtual Private Networks (VPNs), and database backup.

Photo # Radio Ant 11. One of the two Differential GPS antenna's which are normally installed on the yardarm. On HMCS Summerside, the DGPS antenna on the starboard side became unserviceable and was installed in this location as a temporary fit. Because of the cost, it will remain that way and will be the only Kingston-class vessel to have the antenna fitted this way. (Photo by Richard Bungay)

| The Galaxy Sentinel system transmits between 1,626.5 to 1,646.5 MHz,
receives from 1,530.0 to 1,545.0 MHz at a data rate of 600 bps.(Image courtesy Trimble Navigation) |
The Galaxy Sentinel is a fully integrated Global Maritime Distress and Safety System (GMDSS) Inmarsat-C/GPS system. All of the main Sentinel system components are housed in the Communications Unit enclosure including the Inmarsat-C transceiver, GPS receiver, computer, display and disk drive. The printer and antenna are the only other standard components of the system. An optional remote printer, remote alarm panel and AC/DC power supply are also available. The Galaxy Sentinel system offers full compliance with the new Inmarsat CN114 specification and IMO Resolutions A.807(19) and A.814(19). The Galaxy Sentinel system was only fitted on West coast ships and only once on HMCS Summerside.

| Magnavox MX300 DGPS receiver. In 1994 Leica acquired MX Marine Group from Magnavox and in 1997 acquired the Ap Navigator business from Phillips. With this acquisition, MX Marine is able to serve the high end leisure market with the Ap brand products in addition to the Type approved market with the MX brand. On 29th April 2005, Brunswick New Technologies, Inc. acquired the MX Marine business from Leica Geosystems. MX Marine is currently owned by Navico, Inc., who acquired the business in March 2007.
