Model No: 215-470LP16 

FEATURES: 

 

The 215-470LP16 is a dual boom log periodic with more elements than many conventional designs. The extra 

elements help in lowering VSWR and produces higher gains across the working frequency range. The result is a high 
quality commercial broad band VHF antenna. Built for extreme environmental conditions, this design uses 6061-t6 alumi-
num and all stainless hardware and UV stabilized acetyl insulation. Internal stainless screws secure the elements in 
place. Optional models are available with welded elements for corrosive environments or extreme conditions. The 215-
470LP16 antenna can be ordered with many finishes, anodized, chem filmed, or a combination chem film and paint, with 
many colors available.
