[Antennas] Question reg. multiband dipole - balun

[Christian Buenger]

Hello dipole-user,

I have a question regarding a "normal" multiband (80m-10m) dipole. I am 
planning to set up the following antenna: A horizontal flat-top dipole abt. 
2 x 15m long, fed with 450 Ohm window line. So far there are no problems 
but I can't route the window line through the window because the window has 
metal framing. Window line and metal structures is not working ;(

I thought abt. using an external weatherproof 1:4 balun, connecting the 
balun to the window line (outside the house where no metal structures 
exist) and then route coax into the shack (abt. 2-3 meters). Somebody told 
me that this is not going to work. Unfortunately I can't put the whole 
tuner outside. That would make band changes very uncomfortable and 
additionally the tuner is not weather proof.

Has anybody a solution for this problem? Or experience?

Thanks in advance.
