of the camera is 33 cm and the width across the antenna is 18 cm and 13.5 cm across the LCD. As shown the
antenna is placed inside a radome with the edge of the radome approximately 21.5 cm away from the edge of the
camera near the LCD. Keep in mind that the facemask of the firefighter will add an additional 3cm (minimum)
distance to the actual body/head of the firefighter. Note that the radome for this camera system will be made of
Ultem
®
, which has a dielectric constant of approximately 3 (www.cuflon.com/ultem.htm). This will further
decrease the radiated power of the transmitter. Bystanders, we believe, will always be further than 20 cm.
Figure 3 shows the location of the integrated transmitter inside the camera. Note that the antenna is placed in the
center of the radome. In this configuration, the 20 cm distance will be met.

Mr. Agi:
I have reviewed the material that you are preparing for the submission of
the internal FM transmitter for the CairnsVIPER thermal imager and find that
the material represents what we have agreed in our previou meetings.
The images and the dimensions agree with what Cairns beleives to be the
requirements of the FCC for this class of product and we are confident that
K&A has taken all the necessary precautions to make a function and safe
product for the market.
Cairns is prepared to assist K@A in every way possible to achieve
certification of this product with the FCC as well as getting the product
certified for EMI/RFI as soon as possible.
If there is anything that we can do to assist you as our tranmitter
development specialist contact me directly at 1-800-230-1600.
Regards,
Kerry W. Gordon
Vice President of Technology
