If you look at the lightning suppressers as a device to equalize the potential between the shield and center conductor of the coax then maybe it will be easier. Also look at the ground connection on
I haven't tried it on 80 but I don't see why it wouldn't work there too. I did do that on 10 meters. Mounted a vertical element on the 3 element beams boom. Phased them with proper length lines. I tr
How do FM stations manage to transmit dual polarity? What do you think I was seeing when I phased vertical and horizontal antennas together on 10 meters? I found that with severe rapid fading on eith
Hi Jim, The antenna I used was a ta33 and I mounted a vertical dipole out on the end of the boom near the director. I realize it was kind of a crude way of doing it as the beam had more gain than the
Thanks for the comments Jim Lux. How would you account for the disappearance of the signal when switching between right hand and left hand polarization if it were not circular polarization propagatio
I have always been curious why someone would invert the stack. It seems that the mechanical disadvantage of the larger antenna on top of the mast would be more of a problem than any advantage. There

For those that run remote sites, how do you reboot the computer at the remote site if it hangs up? Thanks Gary K4FMX _______________________________________________ See: http://www.mscomputer.com for
Sorry if this seems out of place. I am planing on a remote site several States away from home. Site will include towers, antennas etc. Since several on here have similar sites they operate it seems t

Your steel pipe is probably galvanized? If so you do not want the copper in direct contact with it. Place a sheet of thin stainless between the pipe and the copper strap. Put a stainless hose clamp a
You don't want a zinc clamp. It will be fine with the water pipe but not with the copper wire / strap. Bronze clamps (not brass) are ok with both galvanized and copper. But you still do not want the
Oh oh, now you started it Gene. :>) I will give the first answer. No measurable difference at the other end. 73 Gary K4FMX _______________________________________________ See: http://www.mscomputer.c
I agree with Tom about reflected power not being dissipated in the transmitters final. For all practical purposes, it all gets returned to the antenna and radiated except for the small amount of loss
Here is another way to look at it: With a circulator at the transmitter output and a load on the return port of the circulator, disconnect the antenna line from the circulator. Now all the power out
But where does that "lost power" go? :>) 73 Gary K4FMX _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lo
There will be the same degree of mismatch at the antenna that caused the reflection as there is at the transmitter. 73 Gary K4FMX _______________________________________________ See: http://www.mscom
