Hi,

I am curious why some vehicles have more than one antenna. Sometimes up to 3. Are they linked to the same UHF to give greater range/cover or do people have loads of different accessories inside.

In older vehicles some are probably phone aerials but you see these setups on blue tooth enables more modern ones too.

Just curious really.

Zigdog,

I can't say for any one else but in my case I have 2 UHF radios running at the same time, one on scan and the other on a fixed channel.

I also have a HF antenna and a wireless antenna that is used as a height gauge for the top of the Troopie.

Wayne if the antenna your use for gauging height is "wireless", has no wire"" ..... how do you gauge the height if you can't see it?

olcoolone,

The wireless height gauge is an old CB antenna. It is mounted on the bull bar in front of the driver. It was just the right height to act as a gauge. If it clears any low objects such as tree branches, bridges and car parks, the Troopie with the gas bottles mounted on the roof rack will pass under the object.

I can see the top of the antenna from the drivers seat.

Hi Zigdog,
I have 3. A 6db Desert stick for outback travel to increase range. A 3db spring base ground plane independent mounted on the side of the roof basket and 1 mounting in the centre of the roof for the 3db when I leave the basket off. I have a selector switch to change from the 6db on the bull bar to either of the others. Simple.

On the front bar of out 200 series we have an Iridium satellite phone antenna, on the roof rack on one side we have a 8dB Next G antenna for our Next G modem, on the other side a 6.5dB UHF antenna and on the spare wheel carrier at the back a Codan 9350 Auto tune antenna for or HF radio (yes ACMA we are licensed!).

Bluetooth has nothing to do with external antennas, bluetooth is a data transfer protocol enabling one peripheral to communicate wirelessly with another peripheral (mobile phone to in car phone kit or wireless GPS mouse to laptop).

In some applications an external antenna is used for Bluetooth but more in a commercial environment like a hospital or large office, Bluetooth has a average range of 10 to 15 meters.

Have seen antennas on vehicles for a wireless network (Wi-Fi, WLAN, WiIMAX) giving a range of about 2 kilometres or more.

As well as those mentioned above there are business/work VHF or UHF ones on private work networks, HF CB ones(yep some still around), high gain AM/FM radio antennas, amateur radio setups (lots of different types here) and even antennas to hold up the old fox tail flag.

Found on another site:
Would definitely have to call mine a porcupine.

3 scanners w/ antenna for each
1 2-meter w/antenna
1 dual band (2m 70cm) w /antenna
1 cell phone booster
1 wifi booster
1 VHF (police band)
1 cb
1 am/fm radio
4 T.V (dual phased rabbit ear ) but they stay down until needed.

I thought about combining scanner antennas but it can screw up reception.
