Topband: meters of RG214 i can use

[sasas asasas]

Hi. I have a transmitter and i want to move the antenna to another 
place. I am thinking to use about 50meters coax cable RG214. Except for 
the attenuation i will have, there is any other problem? Problems as 
regards matching and SWR?  I will connect the match system (a series variable capacitor) between the end of the coax and the antenna's feedpoint.
Thank you very much.
