J.B.,

   I take it this is a transmitting antenna? If so, then it will depend on how 
much power you are running and what kind of insulators you are using so you 
don't arc over from the top wire to the grounded tower. It will help if you use 
non conductive rope (dacron) between the tower and the insulator. I imagine 
that your biggest problems would occur if you ran high power and the insulators 
were wet. It would be a good idea to use the ceramic dogbone or other insulator 
with a long leakage path.

Hello Lowfers & LFers,

 

My greatest enjoyment of ham radio is building and tinkering with antennas,

and in keeping with that I'm planning on erecting a "T" or Marconi antenna

which I can use on both the 137 kHz. and the 160-190 kHz. bands.

 

The plan is to have a Y shaped top-load suspended between my 3 towers

at around 15 meters (50 ft.) in height.  Since the towers are grounded, I'll

need to keep the ends of the top load wires a certain distance from them.

 

In searching the web I've found no info on what that distance should be to

avoid problems.   Any suggestions would be much appreciated.
