I saw co-phased antennas crossing 90 degree's!!

[Onelasttime]

So I was at Walmart today getting some antibiotics for whooping cough!!! So I had left my phone in the car. I walk out and what do I see? I see a truck with co-phased antennas on the top of the cab and they are not just crossing as the truck idels away. Nooooo that would not be funny enough the mid point along each vertical was swing perpendicular. 102" whips on 6 inch springs on what looked like angle iron welded to the cab. It was gray and a combination of rain and snow so it was hard to make out perfectly. It reminded me of video's of Giraffes fighting on Wild Kingdom back in the good old days before the internet. That was idling through the Walmart parking lot I hate to imagine what it looks like going down the road 25mph-75mps.....LOL Like two kids fighting with pool noodles! LOL

I freq. see the full size domestic 4x4 or Jeep with a 2-3 foot Firstick mounted on the rear bumper if it is a truck and the rear spare tire mount on the Jeeps. The stud mount is normally lose too so the antenna is never vertical because they drill the hole too large.

I usually do not take my phone with me inside Walmart because I always lose service they only recently opened up their wifi for general use. Subconsciously I probably do not take my phone into Walmart to keep myself from getting shot because I took photo's of someone and broke out in spontaneous laughter. Hard to act normal while framing a shot for the camera!

Us truckers; we do funny things. I often see old cab overs with dual antennas, mounted on the front top corners of the cab, at an angle nearly parallel to the ground, like the truck is a snorting bull, ready to charge.

Either that, or their at about 45 degrees. Then they look like bugs, with long antennas, lol.

I really just don't know what to say except:

Maybe he was just displaying his "X" chromosomes?
Or maybe he was going for the "Circular Polarization?"

For some of those drivers the antennas are angled because it looks cool.

Others do it on classic Pete's or KW's because the antenna is in the near-field of the exhaust stacks and can alter the tunings. I see grain wagons angle them nearly flat for clearance reasons at some of the older grain elevators.

 

[Sarasota Slim]

Another reason for angled antennas, is so that the wind will push the antennas back to straight, when the truck is moving, as opposed to the wind pushing the antennas into a backwards angle.

But, as is often the case with useful modification, folks pick up on it without understanding it, and exaggerate it, then it just becomes another silly trend.

I don't think a big-rig can go fast enough to generate enough wind to make a four foot fiberglass shaft antenna stand up straight.

I used to do it with Frances antennas. Obviously not at the metal base. I used to angled them thinking the same as Sarasotaslim mentioned.

It was explained to me that by the antenna's angeled forward, it somewhat reduces vertical noise and lowers local operators on the sides of the road.
I don't think it does d1ck.

 

[fourstringburn]

Do a quick 90 degree angle and compare, it will be noticeable.

I've known guys who've had this problem.

Agree 110%

the only REASON to angle an antenna is to meet max height regulations,

 

[space cowboy]

You set them up that way when you want to agitate. That way you can't be tracked.

 

[Sarasota Slim]

Are there antenna height regulations for a mobile CB unit? I haven't been able to find any; and I have done some looking. I have found height limits for base stations (60 feet, or 20 feet if on a roof top), but nothing for a vehicle.

That's should explain why those mobile CB antennas that lit up on transmit never became popular.
