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.
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 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.
Not sure , I believe they have used holt allen spars also a two piece mast designed to stow within the boat for transport this was also foam filled to stop a complete capsize. Being a more modern Tupperware type boat I can only estimate the mast to be around 16 foot long as I believe that the boom may be set higher to prevent getting a thick ear whilst gybing.
A wireless laser printer works by receiving a signal from a network server which has wired connectivity. The server can be set up for several wireless devices. The printer will work as long as it is within the signal's range.
It is automatically set when GPS signal is acquired.
A wireless TV sender is used to send the signal from a satellite or cable set top box to a television in another room. The transmitter connects to the set top box by a cable. It then sends the signal to a receiver box which is connected to the television set. The signal is set via wireless and hence there is no need for unsightly cabling.
A platoon (usually between 25 - 40 personnel) specialising in communications. They'll set up long range communications apparatus, set up radio nets, repair radio equipment, etc.
