yes, there will be coupling between the lines where they are close which would couple rf from one to the other, and will also likely upset the impedance of both lines. Hi All Will it hurt to have lad
if you live where there is ice then you want to get the highest wind speed rated one. i went through several rounds of repairs and modifications to get to the point where they live through the winter
feedline length is very important... if it isn't long enough to reach the radio it won't work... anything more is a waste of money. Hi everyone, I've been doing research to determine how important fe
if that picture on the first lot is of the actual towers they have already violated one of the conditions of the destruction, that no pictures be taken! if that is representative of the towers they a
for 1/2" catv i have used a compression coupling and pl-259. cut the shield and foam way back, put the coupling over the hardline and the back side of the pl-259 in the other, tighten down the compre
yeah, i've had lots of fun with hardware store clerks... they want to help but just can't understand why my pipe is full of foam and what that strange silver plated fitting i want to put on it is. an
if you clump them close together the inner ones may not be seen at all. i think its more important to secure them well so they don't blow in the wind and wear on things than to worry about wind area
a "Bracket"? Hi, I saw a photo that got uploaded a few days ago... Inside a small box mounted on a tower was a right angle sheet of metal. On it were double female connectors for cable transits... Wh
all you need to test on the bench is a 12v supply and a couple of jumpers to clip on the motor pins. Hi Gang, In July I asked for help with my rotor issues and my initial notes are below. Today I fin
John's, like mine and many other new installations, use a system that does kind of turn-off... each panel has a micro-inverter that takes the output from the one panel and converts it to 220vac and
trace the wiring from the plug to the motor, if that is like other yaesu rotors it has some filters and diodes bypassed with the limit switches. bypass all that crud and see if the motor runs when yo
it doesn't affect the antenna at all, performance or tuning. How much does velocity factor of coax being used to set up antenna affect calculations for set up. Preformance mabey but what about calcul
practical experience with a 40m inside an 80m 4-square shows it was REALLY BAD! Now that the elements design seem to be established, I was wondering if anyone had modeled the impact of nesting 4SQ st
p.s. an 80m wire 4-square suspended around a 120' tower full of 10m yagis worked ok, but the one that is clear of the towers and other stuff works MUCH better! practical experience with a 40m inside
near field measurements are full of problems also. besides the problems of projecting the near field pattern to something that is useful in comparing in the far field there are all the little distort
now you are in my area of kind of expertise... yes, the ground response to high current lightning is very non-linear. classically it has been represented by an equation put forth by Weck, search for
to do more bands like that you won't be able to just short and unshort the ends, you will have to actively switch the stubs for each band in and out of the circuit. you could do this with a remote an
yes, you can connect all the stubs for a band to a single T connector. The diagram shows space between them but that is not necessary. the only one where spacing is important is the 40m combination o
i would call it a toss-up... pick whichever one is easier, or if you are married, whichever one looks better. I want to determine the best location for the cables and coax to enter my house for my ne
i have two inverted L's spaced 1/2 wave with radials raised about 10'. it is nice because just by switching in a half wave phasing line you can switch from broadside to endfire. I'm starting to think
