Hay, chief, did ya ever think to push the wire down the mast using a
messenger to guide it, like the old wire being replaced, or a fish line? that way, you leave the end with the on deck pre installed connector on it at the top and outside the mast with a drip loop*, while you cut to length and terminate the bottom end below decks, or at the mast base, an easy job, or at least not so awkward as at the top of a wobbly mast, which you heel a bit to guide the messenger. (Damn! dropped the flux, again;-) Is the soldering iron plugged in?) I once climbed to the top of a big fir to cut off the top for a Christmas tree, but dropped the axe after I got up there. Had to go down and up three times all together, once just to get my arms, which fell off next! If you were a masthead radio tech, and not proud of your work, you would have done it again, unless it was your own life at risk. Cobbler's shoes? Dija ever go up just to unscrew, remove and then rescrew the connector, then wait for a radio check after pulling gently on the feeder? It could benefit from doing it once every year. How long do hams spend sending? Rael hams use code, light duty cycle, to set up fax, etc, with old contacts. Or do they want full duplex stereo video to remote studios, at 450 megs using meteor scatter at days' ends, with gigantic yagis doublesteered at the masthead? I saw one like that, once, on a 40 foot ketch in green lapstrake on Grand Lake. Mil RG58 is good enough for most, cheap, light. Communications is our most valuable resource. *Note: A typical drip loop style exit from the mast head would cause compression of the dielectric. Soft cable with long heights hanging should be clamped above the exit hole, sealed with caulk, double clamped or wirehung to the mast, properly sized and torqued, No drip loop, unless needed to meet the antenna mount. Masts should be able to drain at the heel anyway. Matching coils should be below the masthead, 2"-3" away from the mast. Tilting the antenna a little to avoid instrumentation is ok, though it may affect directivity at extremes. Terry K -Yeah, yeah, we *can* build monster cables. -SofDevCo- Hey, Terry! I like it, I like it! Can tell you've been there! Yes, when customers wanted to put the cable in themselves, (Glee!) I would sometimes help them figger a suitable length, and put one connector on in the nice warm shop, advising them to put the cable in, top down, and call me for the bottom connector. When you told of the tree, I initially knew you were bragging about the size of your Christmas tree. Upon closer inspection, I now know that you only used the top! The duty cycle on my 10 meter CW rig is way less than a thousandth of a percent. Usually giving it 8 to 10 months to cool down between contacts. However if one chose some of the FSK modes (I don't, personally), and had a little less than perfect SWR (and 100 watts or so) One can melt or soften current nodes in RG-58. Contributing, one would assume to Global Warming. Old Chief Lynn |
