• Note that the deck flanges are identical to the flanges on our antennas.
• Stainless Pipe diameter are OD 1.5" or  2.0".
• All our flanges are made from Marine Almag or Stainless Steel. We do not use raw painted aluminum in any of our products.
• A propriatory chemical is used to separate the stainless bolts from the Almag flanges to prevent natural electrolysis and the resulting corrosion normally found without this protection.
• Deck Flanges come complete with Stainless mounting bolts, flat washers and nuts. There is an optional cast and threaded backing plate available for both flanges and shown below.
• PR-411 and 414 antennas accept a 1.5" pipe
• PR-420 and 422 antennas accept a 2.0" pipe
• We stock the stainless pipe in 6" and 12" lengths.

 

Shown above is the optional Backing Plate with threaded holes. It can be ordered from stock for both the 1.5" 3-hole flange and the and the 2" 4-hole flange. It is cast with tough marine grade ALMAG aluminum.
