The Multidimensional Alan Borck
By Charles Alan Borck, Founder, RLC Electronics |
Charles Alan Borck, founder of RLC Electronics in Mt. Kisco, NY, died on March 1 at 87.
No one who ever did business with Alan Borck would ever consider him indecisive or indirect. While he was a man of few words, they were always what he believed to be the truth, like them or not. Alan was a stand-up guy, and a very bright one as well.

 Another Sad Moment For the FCC
By Barry Manz
A significant number of rooftop antenna sites owned primarily by wireless carriers exceed FCC public and occupational exposure limits, make it impossible for workers to avoid standing in front of antennas, and are inadequately posted with warnings and barriers. Read More...

•Directivity and VSWR Measurements
Return loss and VSWR measurements are complicated by the finite performance of the directional device used to measure the reflected power. The only accurate and convenient way to make return loss measurements is with a well matched high directivity directional coupler or bridge.
