=========================
microvolts and picowatts are received by the antenna

** Err - it is typically many millivolts per TV channel.

Works out to be around one microwatt per channel.

foofoo... silly factor of a thousand. I do taxes on the side for extra
money. Send me your receipts Phil!

the signal is a few microvolts.

sometimes a higher voltage (like 12V) is fed in the bottom end to power a
booster at the top.

sometimes a tv set will develop a fault and produce a few hundered volta on
the antenna socket I've measured about 400V throug a resistance of about
2Mohms, other than giving a nasty suprise to anyone who touched the antenna
the TV was working fine.

** Like hell it is.

With dozens of UHF and VHF signals in an urban area - the total RF signal
voltage can be 100mV or more .

A single analogue TV signal needs to be above 1mV for a noise free pic.
