UHF CM4221HD (Hacked) - No Reflector
1. UHF CM4221HD (Hacked) - No Reflector  (18 Oct 2013)
UHF CM4221HD (Hacked) and NO Reflector analyzed using 4nec2.

CM4221HD measurements per fol. smpowell55 posts:

UHF Raw Gain = 7.4 to 12.2 dBi and SWR (300-ohms) under 2.6.
Hi-VHF Raw Gain = 4.1 to 4.2 dBi and SWR (300-ohms) = 17 to 1.1.
SWR on Ch7-10 degrades Net Gain & EVM (Error Vector Magnitude), but may be adequate for strong stations.
NOTE: As-shipped PCB Balun KILLS VHF.  Above Hi-VHF performance presumes replace with
conventional Transformer (Cylindrical) Balun.

BowLength = 7.9-in, Inner-Inner Bowtie Spacing = 9.84-in, Outer-Inner Bowtie Spacing = 8.46-in,
Tine Separation = 3.94-in.  Feedline Separation = 1.18-in, with 0.8-in at Crossover (2" from Outer Bowtie).
16 Rod Reflectors: 23.6" Long with 1.93" Spacings for Total Height = 30-in.  Separation from Bowties = 4.25-in.

It is presumed that anyone interested enough to view this webpage will
implement the "Hacked Balun" modifications per photo in fol. rabbit73 post
(flip over the Feedlines going into the Balun plus an additional offset):

wood chipper
8. wood chipper 
Decided it was time to a medium size chipper to smaller jobs around the farms. We need something that will chip up the smaller limbs as we cut and use most everything over 2 inches in diameter. When we clean fencerows and such we'll burn those. When a single tree or large branch falls in a field it will be a lot nicer to chip it and blow it in the fencerow where a bush hog will spread it out. A plus will also be with other cleanups I can simply blow in the back of a truck to save hours of limb dragging or multible  brush loads with the truck.

 I wanted a PTO powered version with a power infeed system. Did some comparing of different ones and decided on a WoodMaxx. It will handle up to 8 inch material, which is more than I need but it's nice to have the option! Should be a strong unit that will last. Here is a  review and how it is working for us.

EAB cleanup
11. EAB cleanup 
Here is an album of the clean up project at my place. EAB (European Ash Bore) has or will kill all the ash trees around here. The small woods behind my home was mainly ash so it is devastated. It had also been overgrown with honeysuckle which we had not been taking care of. I will now get rid of the stuff and clean up all the dead ash on the ground. That way I can leave the standing dead till I have room for them here. I will seed grass and when the dead are out I will replant some trees so there is something up there. If I plant now I'm afraid of smashing them when felling what's left.

Taken with the Panasonic FZ20 in continious mode. Note the speed between the 3 frames. OK it's not 100 sharp but worth keeping.

I have added a few more pictures.
