The time it takes for a TV signal to travel from the TV mast to your set is typically a fraction of a second, usually around 1/1000th of a second or less. This is due to the speed of light, which is approximately 299,792 kilometers per second in a vacuum. However, factors such as signal processing and transmission delays can add a few milliseconds to the overall time. In practical terms, the delay is imperceptible to viewers.
The time it takes for a TV signal to travel from the TV mast to your TV set is virtually instantaneous. The speed of light, which is how the TV signal travels, is approximately 299,792 kilometers per second in a vacuum. The distance between the TV mast and your TV set is relatively short compared to the speed of light, so the signal arrives almost instantly. This is why you can watch live broadcasts in real-time without any noticeable delay.
a mast
The mast mounted amplifier will amplify only what is coming out of the antenna, while a set located amplifier will also amplify any noise that was induced in the lines between the mast and the set.
A diplexer is a box that combines both signal usually mounted on the aerial mast . At the tv set another box separates the two signals,one to tv the other to sat digibox
The signal will move down the cable at from about 1/3 the speed of light to about 9/10 the speed of light, depending on the type of cable used. If there is a booster amplifier in the cable between the antenna and the TV set this will add more delay. You will need to know the length and types of cable used (and look up their signal propagation speed) as well as the delay of your booster amplifier if your system has one to calculate the answer to your question.
It would take you 2-3 years to set it up and to take it down 2-3 years aswell and that's a long time
It depends. If you are working alone, expect it to take a few hours to do. If you have people helping you, it will not take as long.

A Ketch is a sailing vessel with two masts, a main mast and a mizzen mast abaft. Very similar to a Yawl the main differences being a ketch's mizzen mast is forward of the rudder post which in turn gives the ketch a larger sail area. A ketch's mizzen mast is used for propulsion where a yawls mizzen mast is used for trim and balance. Ketches are very common among long distance sailors, since the larger sail area gives you a better balance. Also a ketch allows you to drop your mainsail in sudden wind gusts and sail only with your jib and mizzen set.
Generally not. The signal is of a different type but you can get a set top box converter to downgrade the signal to SDTV levels. They're costly (Around $200, give or take) and you might just be better off using that money for a digital set.
