Dear friends,

That is the situation I am facing right now.... After many years operating with 
a vertical antenna I moved to my own apartament 
and got permission to install a small tribander Yagi. I decided for a 2 element 
Yagi simply because it is small and is discreet. The antenna was installed on a 
18 ft self supported tower, however, for safety reasons,  I installed guy wires 
at each 90 degrees (the tower has a squared base).

Well, the only place I have to bring the coax and rotor cables from the roof to 
the second floor (where is located my apartment) is the same place where the 75 
ohms antenna tv cable passes. Does anyone have experienced the same situation? 
TVI will happen for sure? The antennas (my 2 el yagi, the VHF tv antenna and 
the directv dish) are very close up there anyway. The only place available to 
install antennas on the roof is an area of 24 ft x 12 ft. 

I am asking that (and do not try directly) because the cable will show up in 
the main room and I will have to break the floor or the the wall to bring the 
cables to the shack. Big work... big problem with the wife. If TVI is sure I 
will have to start again the lobby work with the neighbors to pass the cable 
outside the building (this second option is hard to accomplish).

I would like to hear some comments.

73 and thank you in advance
