[SCCC] [TowerTalk] Anyone know the CURRENT Los Angeles CountyZoning Rule...

[Michael Tope]

Yes, but if I remember correct didn't you get a C.U.P., Bruce, whereby 
all your neighbors had to be notified of your intended installation? 
Seems like they would have been aware ahead of time that you were 
supposed keep the thing cranked down whereas with a non-CUP installation 
they would have to do more homework. That's why its good if your 
neighbors don't have any teeth since that makes it less likely that they 
will be lawyers (or worse yet engineers) :-)

Art's point about TVI/RFI is good. I do seem to hear lots of stories 
about ham stations causing interference even when they are not powered 
on :-)

Craig's comment reminds me of my grandmother's neighbor from when I was 
back in college. He was a cool old guy who let me put one leg of my 80 
meter inverted vee up in his tree.  He told me that he could always tell 
when I was home on break from college because his automatic garage door 
would start going up and down by itself. In this case the RFI was real, 
but he didn't really seem too upset about it  :-)

In my case the top antenna is at 107 feet when the tower is completely extended, and it's at about 70 feet when cranked down (lower height limited by a tree, rather than minimum height of tower). After erecting the tower, I gradually started leaving it completely extended for long periods of time. About a year after I erected the tower, I received a call from the city planning office reminding me of the limitation specified in my permit as to when the tower could be fully extended. The call was in response to a complaint from a neighbor 5 houses away. It's likely that the height is more noticeable from several houses away than from next door neighbors.

>>Good point, Kurt, and one worth pressing.  Not only can there a substantial difference in cost between a crank-up and a fixed tower, but a tower that must be lowered cannot accommodate semi-rigid transmission line (e.g., Andrew LDF series) often used for VHF and UHF operation.

>>Further, most telescoping towers were not designed to be run up and down regularly; doing so would cause premature wear on pulleys, cables, etc. and could actually increase risk of mechanical failure.  The telescoping feature is generally employed to facilitate installation of the tower itself and antenna installation, maintenance and adjustment.
