Just a thought - but if its temporary, why bother making up ladder line ?
I would be stringing up some tv twinlead

I'm installing a temporary V antenna with a 600 ohm ladder feed about
50 ft in length. Anybody have experience using 6" wood dowels as
separators? What happens when it rains?


If you intend using the antenna on frequencies where its length is less than
a quarter wave; the losses on 300 TV twin lead can be very high. Also you
will likely exceed the breakdown voltage of the TV twinlead. On 7MHz, and
above, the TV twin lead will be acceptable.
