Multiband Antenna Traps

Avoid switching wire antennas to work different bands. trap

Use Unadilla’s W2VS high performance traps to convert your single dipole into a tuned, multiband wire antenna. You can also use these traps to design HF vertical multiband antennas using either wire or aluminum tubing. Traps for different bands can be combined onto one dipole to create a single antenna tuned for maximum gain on all your favorite bands, from 160 to 10.

W2VS traps are available for 80 meters and up in two versions. A FREE trap design guide is provided to aid multiband dipole construction. Rated for 2KW PEP. Built from stainless steel and aluminum hardware to resist corrosion, these rugged traps have a pull strength of over 600 lbs. Trap coils are waterproofed and condensers are epoxy-sealed.

W2AU 1:1 & 4:1 Wire Baluns

Filed under: Baluns, New Products — Tags: , , , , — admin @ 4:04 am

long the standard of the industry the W2AU baluns are built to last!

The W2AU is the preferred Balun of Amateurs worldwide. W2AU’s operate at a low VSWR from 1.8 to 40 mHz, and handle powers up to 2 KW PEP (at SWRs of less than 3:1). W2AU Baluns are transformer designs with ferrite cores to provide 95% minimum coupling efficiency. Each has a built-in lightning arrestor, hang up hook, and 600 lbs of pull-apart strength in a weatherized, rugged package using only stainless steel hardware and quality materials. Two models are available. The 1:1 matches 50(75) ohms unbalanced coax to 50(75) balanced dipoles. The 4:1 matches 50(75) ohm unbalanced coax to 200(300) ohm folded dipoles.
