I looked up the meaning of the word "mast" in the Oxford Encyclopedic 
Dictionary [1]. The meaning No.3 is:

tall steel structure for the aerials of a radio or TV transmitter.

In the article of the word "tower" in this dictionary there is nothing 
about a radio, TV, or communication.

In the Cambridge Advanced Learner's Dictionary [2]: for the word "mast" 

RADIO/TELEVISION 2. a tall metal pole used to support an AERIAL for 
radio or television signals: a television/radio mast

for the word "tower" meaning No.2
a tall, usually metal structure used for broadcasting: a 
radio/transmission tower.

Google search of "radio mast", "radio tower", "television mast", 
"television tower", etc. gives each millions of results with similar 
images. It seems that the words "mast" and "tower" are interchangeable. 
The article in English Wikipedia is called: "Radio masts and towers":
