[TowerTalk] personal rf meter

[CARY GOOCH]

Hello List.
 
Seems I am back on the towers after years of being a flatlander, and
have some questions for the list members. I am often working at a site
with more than one tower, and not sure in which direction other rf
sources may be pointed.
 
Is there a device that I can wear (and not be in my way) which will
alert me of rf dangers?
 
I am also interested in finding the software that will give me a side
view along the line of sight. That is given the coordinates of two
towers, and the height of the antenna on each, a graphic that will show
ground clearance along the signal path. Would be helpful in deciding how
high each dish should be.
 
Sorry if these are newbie questions.. I have not climbed in years, and
RF engineering has some areas of consideration unfamiliar to me.
 
Best regards,
Cary
