Overview of “multiband traps” says they are available in 2 versions but I only see one version in detailed description ??
#2 by Unadilla on May 19, 2011 - 10:13 am
The other versions are mostly customizing of the traps for special purposes such as beam, frequency,
single units etc.
Call or email for specific application assistance.
Thank You Unadilla

I want to put together a 160 and 80 meters trapped dipole, what traps do I need?

Rick at one time an adjustable band was offered by Microwave filter, it created to many problems, so we discontinued it. We nor only offer the best type, fixed frequency trapped pairs.
Thanks for reminder to edit that info.

I am a Stroke patient, so the left side of my body is not working, and would want to like to ask is the W2AU/W2VS could be supplied ready to `hang up`, all the cables to the traps, balun, and end sulator etc, and all attached to the cable?

Yes, sir. For a 10/15/20 antenna you could use a KW10 and KW15 meter trap pair. Then the antenna wire out to 20 meters. These lengths would be, from the Unadilla Balun, 8’2″ to the 10 trap then 2″4″ to the 15 trap , then 3’11″ more or less to your desired center frequency at 20. The tap booklet comes with the traps. You can request a mailed copy if you wish.

I’m building and inverted “L” onto my Hustler 4btv, and only need two traps, one for 75m and another for 40m. Can they be purchased singly? I read the price list as quoted in sets (pairs)…. ?
Tnx, Jim K9JFK

I just purchased and received from you, 10m, 15m, 20m and 80m traps. These traps were received with no eye bolts on the ends. The last time I order a set of traps, the set had stainless steel eye bolts attached on each end. Were they left off by mistake or do you not supply them now?

Hi, I’m wondering, I’d like to construct a two (2) band dipole using your traps. I’d like it to be 15 and 20 meters. I have very limited space and wondering what the physical lengths of cable/wire would be required from the balun to 15 meter trap and beyond per leg. Thank you for your time.

I bought a pair of KW-30 traps a year of so ago and finally have some time to build a 40/30 meter dipole. I seem to have lost the design guide. Can someone help me out with either a copy of the guide or the wire lengths?

I’m puting up a multidipole antenna and I was given W2AU 1:1 balun, I think. It has a white tube with black end caps and W2AU stamped on the top cap. I’m not sure if it is a 1:1, the paper information either wore off or was ripped off.
How do I check if it’s a 1:1?

I want to make a three element two-band WARC yagi beam 12 and 17meters.
Could i use 3 pairs of KW-12 traps for this, or does the reflector and director traps need to be tuned for slightly different frequencies than the active elements?
is it enough to tune the lengths of reflector and director elements accordingly only?

I am WA4YBC, and have been licensed since 1965. In the late 60′s, I had a 2 element W2AU cubical quad, first with bamboo spreaders, and then with fiberglas spreaders. This was the best antenna that I have ever owned and operated. I would really like to own, or build a similar antenna. If you have any information, or parts, that could help me build your W2AU Quad, your help would be appreciated.
