So what does this do to the SWR??

To this day, I have NO idea how in the hell the antennas end up like this. There is nothing on the overhead door that would do this. I am begining to suspect a noctornal antenna twisting gremlin that lives in the attic. I am wondering what this does to the SWR of the antenna....

SWR, or whatever...

Matt:

It sure isn't a 50-ohm match any longer at the main frequency you're using. Looks like lowband so probably not as bad as it would be if you were on were 155 or 460 mHz.

As far as the garage doors are concerned, it's much worse to hit the windshield frame and break the glass than to just bend the antenna. I saw a guy do this windshield trick on a '31 Alf Metropolitan once in his rush to get out of the house; he really caught hell from the chief. Just impatience and nothing more.

That's the top-loaded "capacitance hat" style antenna that was used in low HF systems!

Seriously, I have seen departments do this so it 'slides' along garage doors or ceilings easily.

I hit a bird with my Larsen lo-band, and it looked just like that when I got the little sucker unwrapped from the antenna...

Bird didn't make it.

Yea, it helps the signal bend around all the morons who can't figure out what the big YIELD signs mean. :P

Out here, you have to remind people that it's YIELD, not GIVE UP....

You might look at low tree branches, low wires and low bridges. I couldn't believe just how much a whip can be reformed when it hits something at road speed.

I use to wonder just how it happened untill i did it on one of my roof mounted whips. I remember hitting a low tree branch one day. When I got home, my whip looked much like the picture. I straightened it up and hit the same branch about an hour latter. Had the same results the second time around.

In SC, you have to remind people that Yield doesn't necessarily mean come to a dead stop. Also that Stop doesn't mean roll through it...

Yield signs are ignored around here and stop signs are interpreted as yield signs... oh and what are all those funky symbols under 'SPEED LIMIT'?

You know, I could almost understand it years ago when they just had those tiny little faded yied signs. But now the state put in these MASSIVE yield signs (like the size of a honda) and these HUGE signs before you get there telling you what to do. And people still don't get it. It is beyond me how no one has been killed in there yet. It's really funny when some jackass comes down the hill on Rt. 79 doing 80mph+ and thinks they can take the circle without slowing or stopping. :evil:

Mike, sit at Circle Pizza and while your eating lunch, just watch the circle. If you bring a camera, you can film an episode of Worlds Dumbest Drivers XXIV.
