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.

Refer to the horizontal or vertical mounting options pages to chose connector mount bracket location. 2. locate the Feedline RG-303 with connectors. Feed the SMA female con- nector end of the cable inside the boom starting from the cable access slot.
- Page 6 215-470LP16 ASSMBLY 3. Note the picture of the feed nose assembly, locate the grounded side of the feed nose assembly. Warning The feed nose assembly when unattached is fragile, after complete installation it will be very durable. Care must be taken during the following steps.
- Page 7 215-470LP16 ASSMBLY 5. Carefully slide the cable and feed nose assembly back into the boom assembly, align the grounded side of the feed nose assembly with the hole in the front of the boom assembly and add the 8-32 x 3/8 screw.
- Page 8 215-470LP16 ASSMBLY 6. locate the front and rear delrin spreader bars. Add the both smaller front spreader bars to either side of the boom assembly add the 8-32 screw thru the boom and add the nut. Repeat for the rear end of the boom as- sembly.
- Page 9 215-470LP16 ASSMBLY 8. Locate the BTM side plate, BTM block and mast mount plate. See the picture and assemble the BTM bracket. Add the u-bolts and uni-cradles for your mounting style, horizontal or vertical polarity. Be sure to tighten all hardware before installation. Always use good low loss coax for feed line.
