Re: High-Q Mini-Loop for Ultralights

Hey Russ:

Mine was different than the one the Ebay seller has now. Mine was made
from 180/44 and cost $21. The 220/46 he has now probably has a bit better
Q across the band, but cost $30. I get the sense that he might make
whatever people want, so you might want to contact him if you're
interested in one like mine.

What was the cost of the loop coil ?

Hi all:

I just posted a couple photos of a recent project on the UltraLight DX
Yahoo group. I recently got a high-Q basketweave loop on eBay from the
seller "noseknowsnose" . It's a 3.5" Litz coil with a Q around 800. I
popped it into a small plastic box designed for old PC diskettes, used
double-stick foam tape to put a 2x260 variable cap on, and Voila! I
stuffed some tissue in the box to keep the coil from bouncing around -
really high-tech at this point...

The high Q of the loop really adds tuning sharpness to UltraLights,
making it easier to shade one sideband over the other or notch a pest
out of the way. The gain is pretty good as well.
