was sent to us by Mark in Wheaton, IL.*

Here's what Mark had to say...

Denny, Follow-up: The Stacker works great in my attic. I added a 10db
amplifier near the antenna and channel 2 (CBS) is at 89% signal strength.
All the other channels moved from 85-90% strength to 100% strength! As I
have said in an earlier email, we have tried several other antennas without
any success (even with amplifiers). Channel 2 just would not come in
consistently.
Now we do not have to put a new antenna on our roof after we get it re-done
this spring!
Great product, thank you!

2002 Indoor multiband dipole 20m -10m (to scale)


New (2005) indoor multiband dipole 40m -10m (not to scale)
15m dipole replaced by 40m/15m short-dipole, see below


Antenna wires connected in parallel to HyGain BN-86 Balun


Antenna wires attached to roofspars
Spacing between wires = 0.2m, spacing between roofspars = 0.6m


5.3 uH loading coil, 54% from feedpoint (21 turns on Amidon T200-2)
to fit 40/15m dipole in roofspace (total span 15m)


Detail of end-insulator with wires folded back and twisted
for fine tuning the dipoles for the lower frequencies
