Topband: K9AY amplifier

[Wojciech Tomczyk]

Hello OMs,
I plan to build a K9AY antenna.My question is about location of its preamplifier.I consider locating it inside the control box at the base of the antenna.Does it have any advantage/disadvantage? I am concerned about signal strength loss in coax between antenna and radio if amplifier is located at the receiver side.I do appreciate any comments-
