Hi Ron, 


A simple installation should be adequate if you're not planning in-band 
receiving capability while you're transmitting. Otherwise more extreme 
measures may be necessary to avoid micro-arcing, such as bonding 
tower sections together and bonding the upper ends of guy wires to 
the tower or insulating them very close to the guy attachment.

Howdy All, 

I'm getting ready to put up a Rohn 25 Insulated Base ~1/4 wave vertical. 
(115') and I'd like to get some advice if possible. 

I'm using guy brackets. Any reason to use Insulators between the Big Grips 
/ Phillystran and the brackets like is recommended on higher bands ? 

Any preferred goo or concoction to put on the tower sections before joining 
them ? Or nothing ? 

Any other advice on the tower / radiator itself from folks that have BTDT ? 

My plan is 115' and I'm using a Rocket Top at the top. Without any mast I 
will have my 115' but I plan to insert a mast into the rocket top (8') and 
have it Inside the tower, not extended above the top. I figure if it 
resonates too high I have 8' to play with up top. 

Thanks, Ron, WV4P
