Bull****. Transmitters get knocked off the air, and the anteanna

People who are more than TV repairmen learn from their mistakes and
correct reasons for that failure. TV repairmen only fix defects -
never bother to learn how those failures can be avoided. Let's have
some fun. Let's reply using the same mockery and insult that Michael
uses. Except this post will be accurate about Michaels intelligence.

Others who bother to learn discover what happens when a radio
station repeatedly gets knocked off the air. Eventually that station
engineer may hire someone who knows more than a TV repairman. What
was the solution to so much radio station damage? They fixed mistakes
made by a naive station engineer. They installed and upgreaded
earthing. No more lightning damage.

Michael will deny reality because Michael knows without first
learning facts. Others can learn what Michael Terrell denies.
Lightning need not cause damage when one thinks, instead, like an
engineer. Michael Terrell who learned to think like and engineer -
not like the technician - would know this. Radio station repeatedly
damaged. Then they finally admited that failure is not acceptable:

Based on a belief that "too much" grounding was attracting
lightning strikes, grounding connections on the tower's six
sets of guy wires had been disconnected sometime in the
past (Figure 4). This action may, in fact, have helped direct
lightning discharge current down the antenna tower itself,
bringing the strike closer to the studio/transmitter building.


Why did the station engineer make damage easier? He could not
bother to learn about stuff even published in QST magazine - the ham
radio operator's magazine.

Why does Michael Terrell deny this? He is a technician - a TV
repairman. His posts attack the messenger rather than address
technology. Michael Terrell is correct. Some stations are knocked
off the air by lightning. Those with informed station engineers
correct the defect - learn from their mistakes and eliminate future
failures. Michael Terrell's attitude declares failure as acceptable.
But then Michael Terrell could not think like an engineer which is why
he also could never be promoted above enlistedman.
