A 9:1 impedance transformer brings the varying but generally high antenna impedance down to something reasonably easy to match to 50 Ω. The transformer approximately matches the unbalanced coaxial feedline to the unbalanced end-fed wire plus a short counterpoise. Hence the name, an unbalanced-to...
antenna onto a parapet with a step difference by placing the 1st and 2nd concrete blocks onto a slab face in the inside of the parapet, placing an antenna pole seat while bridging over them, supporting a middle part of an antenna pole and inserting its root to a metal placed on the ...
The theory says that the outside cable must be connected to the negative pole to the coaxial cable does not act as an antenna, I have not only the inside and it works. the extent of signal has been multiplied by 4! 4 to 16 meters! Now the robot can move around the house without ...
A composite building panel including a central body, substantially parallelepipedic in shape, comprised of an expanded polymer matrix, having a first surface and an opposing second surface; and one or more structural reinforcing elements longitudinally extending across the central body between said oppos...

point at which the boom is sheeted to be moved from side to side, giving more control over sail shape and angle to the wind. That is the horizontal rail-like object atop the arch, and that wonderfully arcane vertical thing in the foreground is a dual-band J-pole antenna for amateur ...
eleven The sheer clamps (the stringers glued on back in step three) are planed to accept the deck panels using a template provided with the kit. twelve Decks are prepared for installation by applying a coat of epoxy to their undersides. thirteen The deck is installed in two operations: firs...
