installing a mobile mount
hi,
after some soul-searching, i'm seriously inching towards hard-mounting a long whip on the top of my car. does anybody out there know of any relatively foolproof -- and definitely leakproof! -- procedure for intalling a roof mount? i'm considering one of those ball mounts, so that i can easily adjust the whip angle. i should mention that i do have a luggage rack, so i could always attach to that. i am a bit cocerned, though, that the stresses placed by a 'whipping' 102" whip on a luggage rack might be too much for it. any thoughts on this? thanks much! thor |

You might consider using two antennas -- a shorter one for the road and the 102" for when you are parked. If you think you will be swapping antennas frequently, you can get quick-disconnects that will fit the standard 3/8-24 base thread. I would recommend mounting it in the center of the roof without a ball-mount. If you are going to use a ball-mount anyway, it might be better to mount it on the side of the body or the bumper. Above all, avoid the cheap ball-mounts. They frequently slip, and when they do you will end up driving a screw inbetween the two pieces just to keep the whip off the ground. As for waterproofing, the large rubber gasket and teflon/poly insulators that come with the mounts do a pretty good job of sealing out the water. The stud and antenna should also have rubber/teflon/poly O-rings to keep water out of the threads. If you are really concerned (or if you live in Seattle) you can take the mount apart every couple months or so and check for condensation and corrosion. A couple tips: sand away the paint for an inch or so around the hole (on the inside of the vehicle), then clean the bare metal with a good solvent so you get a good ground connection. Also, I have noticed that many newer vehicles don't have very thick metal up top, so sometimes I add a sheet of steel or aluminum to stiffen things up. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

This is what I did to install a significantly lighter antenna in a roof center mounting. The 7900 is a ham 2 meter antenna, about 5' long or thereabouts, with no bend to it whatever. |

I hope our summer is nowhere near the severity of what winter brought to the states. Chasing is like that. Spotting is a little different. We don't travel a whole lot, but I may rack up 100-300 miles in a day, running all over the county doing spotting before, and damage assesment after. Hurricanes you get more warning of. We get maybe 3 days notice that conditions will be right in our area, but as to the actual warning of the event, we are literally the first to know. I had a reporter along with me season before last, who got way more of a ride than he expected. He kinda paled when EMA ordered me to evacuate my position because of a radar indicated tornado heading straight at us. It was covered by rain from where we were, so we couldn't see it (or much of anything else) at that time. The plan had been not to try to outrun this storm, a large flanking line, but to wait till it passed , and then follow.. The cell that went by us, later did tornado, and then went on to level Van Wert Ohio. |
