I find it helps if you finish off the pizza first.
The Q is increased quite a bit. ;') Steve --- qrpbear <qrpbear@...> wrote: Scott, __________________________________ Do you Yahoo!? Friends. Fun. Try the all-new Yahoo! Messenger. |

I just left it inside... after a week or so it gets nice and stiff.
Makes for good re-inforcement of the box. 73, 'Bear' NH7SR --- In loopantennas@..., Steve Greenfield <alienrelics@y...> wrote: I find it helps if you finish off the pizza first. |

开云体育well tried an experiment tonight took the?yaesu
frg-7700?and look outside and the pizza box loop and from what I see the
loop is more directional closer to ground and seems to work better on some
stations. Also the tuning cap needs to be very finely tweaked to peak the
station its amazing how just adjusting it can change the sound of the audio and
or remove adjacent interference. also the loops works just about as well as my
big dipole only quieter most of the time the bonus is the size of it the loop is
much much smaller and works just as well if not better on some station because
of its directionality. I am very impressed with this MacGyver antenna or MPBL
for MacGyver Pizza Box Loop hehe. I also took and used some hot glue to secure
the turns?in 4 spots on each side also on the corners I may take some pics
later for you guys its ugly but works great. Also thanks to everyone who
suggested ideas and what not and a big thanks to bear for the
description.

Ah, shucks, Scott! ('Bear' sheepishly grins and scuffs his foot)
Thanks! Sounds like you've got a pretty high Q loop. I have noticed a small degree of sideband cutting on mine at the low end of the band. The polyvaricon cap I'm using is probably cutting down on the overall circuit Q. Not surprised that you got better directionality at ground level. From about 3 MHz on down rf seems to like "falling down" and traveling along the ground. Same thing happens with acoustic waves. The lower the frequency, the more they hug the ground. 73, 'Bear' NH7SR --- In loopantennas@..., "Scott Savage KC7WDG" <kc7wdg@c...> wrote: well tried an experiment tonight took the yaesu frg-7700 and lookoutside and the pizza box loop and from what I see the loop is more directional closer to ground and seems to work better on some stations.
