WSP cars question! :)

[SCPD]

Since we're on the topic of WSP, I have a question about their cars

What are these antenna's? The one of the roof is the VHF antenna I believe for their radio system, what are the ones on both sides of the vehicle? I didn't think WSP had CB's in their cars anymore? Or is it something different? Thanks sooo much again! This is what makes our radio community great, us! Happy Holiday's!

I'd take a guess and say the roof antenna is for the MCN (computer); the right side fender is the VHF, the left is a CB.

Thanks, do those long VHF antenna's work the same as these ones?

Are the longer ones better or something?

In my experience, the longer ones with the base loaded coil have better gain than the shorter quarter wave models.

Anyone wanna chime in, if even just to call me dumb?

Roof mount is a dual band VHF and UHF. The VHF on the fender is for the second RX'er. The other fender is for Children's Band.

In my experience, the quarter wave antennas work better in "urban canyons" because they direct some of the energy upward. The 5/8 wave antennas work well in rural areas as they direct most of the energy outward (which, I believe is pretty much the definition of gain).

On another note, a porcupine I recently worked on had:

VHF 5/8 wave voice antenna
800MHz scanner antenna
2.4GHz WiFi antenna (to use the client's on-campus data network)
700MHz/1.9GHz LTE/4G antenna (for cellular data when off campus)
GPS antenna (for vehicle location)
UHF gain antenna for interoperability
