monitor one or more of an environmental condition, or condition of the deicing assembly,

send a signal to said controller indicative of a current monitored condition, and

cause said controller to trigger the initiation of cycling of inflation and deflation of the pneumatic tube of the de-icing assembly upon receipt in the controller of a signal indicating the presence of a predefined condition;

wherein the at least one sensor includes a wind sensor configured to send a signal corresponding to a measurement of a direction and a speed of a prevailing wind at the communications tower, and

wherein the controller is configured to determine which of a plurality of de-icing assemblies to cycle based in part on said wind sensor signal.

2 . The de-icing system of claim 1 , wherein said controller is in operative communication with one or more of said air supply source or a controllable air valve disposed between said air supply source and said de-icing assembly, and is configured to activate and deactivate the air supply source or actuate the air valve between an open and closed state to cause inflating air to selectively inflate or deflate the at least one pneumatic tube of the de-icing assembly.

3 . The de-icing system of claim 1 , wherein the at least one sensor includes a temperature sensor configured to send ambient air temperature signals to the controller, wherein in response to a signal indicative of the ambient temperature at the tower being at or below 32-degrees Fahrenheit, the controller triggers initiation of cycling of inflation and deflation of the pneumatic tube of the de-icing assembly.

4 . The de-icing system of claim 1 , wherein the at least one sensor includes a moisture sensor configured to determine the presence at the communication tower of moisture in the form of snow or ice, wherein in response to a signal indicative of the presence of snow and ice at the communication tower, the controller triggers initiation of cycling of inflation and deflation of the pneumatic tube of the de-icing assembly.

5 . The de-icing system of claim 1 , wherein the at least one sensor includes a pressure sensor configured to measure pressure within the at least one pneumatic tube, wherein the controller is further configured to cease cycling an inflation and deflation of the pneumatic tube in response to a low pressure signal from the pressure sensor indicative that said one or more pneumatic tubes has ruptured.

6 . The de-icing system of claim 1 , wherein the at least one sensor includes a pressure sensor configured to measure pressure within the at least one pneumatic tube, and wherein the controller is configured to trigger a cycling of the inflation and deflation of the at least one pneumatic tube in response to a signal indicating the presence of an elevated pressure that is higher than an expected threshold value, which is indicative of accumulation of one or more of heavy snow or ice on the pneumatic tube creating increased pressure therein.

7 . The de-icing system of claim 1 , wherein the at least one sensor includes a pressure sensor affixed to a component of the communications tower adjacent said de-icing assembly and configured to measure an increase of pressure directly on said sensor cause by accumulation of snow or ice, wherein said controller is configured to trigger the cycling of inflation and deflation of the at least one pneumatic tube in response thereto.

8 . A method for mitigating the accumulation of snow and ice on a component of a communication tower, comprising:

affixing a plurality of de-icing assemblies to a plurality of components of a communication tower, the de-icing assembly having a backing member, and at least one pneumatic tube disposed on a front facing of said backing member and defining an expandable chamber configured to be selectively inflated and selectively deflated;

detecting the presence of an accumulation of one or more of snow or ice on the component of the communication tower or the at least one de-icing assembly, the detecting step comprising:

monitoring, by at least one sensor, one or more conditions at the position of the de-icing assembly on the communication tower, the at least one sensor including one or more of a temperature sensor, a moisture sensor, a pressure sensor, or a wind sensor, wherein said monitoring step includes measuring, by the wind sensor, a direction and a speed of a prevailing wind at the communication tower;

sending a signal from the at least one sensor to a controller configured to control operation of the de-icing assembly, the signal corresponding to a current state of the condition being monitored;

determining, by the controller, the signal meets a predefined threshold criteria indicative of the presence of one or more of snow or ice on one or more of the component of the communication tower or the de-icing assembly;

determining, by the controller, which of the plurality of de-icing assemblies to cycle based in part on a wind sensor signal received in the controller; and

periodically cycling inflation and deflation of the at least one pneumatic tube in response to a detection of the presence of one or more of snow or ice on the component of the communication tower or the de-icing assembly, causing the snow or ice to break free from, and fall off of, the component of the communication tower and pneumatic tube affixed thereto.

9 . The method of claim 8 , wherein:

said monitoring step comprises measuring, by the temperature sensor, ambient air temperature at the location of the de-icing assembly; and

said determining step comprises determining, by the controller, that the signal received from the temperature sensor indicates that the ambient air temperature is at or below 32-degrees Fahrenheit, as the predefined threshold temperature criteria indicative of the presence of snow or ice on.

10 . The method of claim 8 , wherein:

said monitoring step comprises monitoring, by the moisture sensor, for the presence or absence of moisture in the form of snow or ice at the location of the de-icing assembly; and

said determining step comprises determining, by the controller, that the signal received from the moisture sensor indicates that moisture in the form of snow or ice is present at the location of the de-icing assembly.

periodically activating, by the controller, an air supply source to supply inflating air to the pneumatic tube of the at least one de-icing assembly causing inflation thereof and expansion movement of a pneumatic tube surface on which the accumulated snow or ice has settled so as to cause the snow or ice to break free from, and fall off of, the pneumatic tube of the deicing assembly and adjacent components of the communication tower; and

periodically deactivating the air supply source causing the air present in the pneumatic tube to be evacuated or released therefrom, thereby deflating the pneumatic tube and further causing additional of the snow or ice to break free and fall therefrom.
