Ground Your Antenna Mount If you’re using a standard CB antenna (i.e., anything except a no ground plane, or NGP, kit), you’ll need to make sure your antenna mount is solidly grounded to the vehicle’s chassis. A bad ground will result in an un-tunable antenna and sky-high SWR levels.

What is the legal height of a CB antenna?

For houses and buildings up to 15 metres high. an antenna mounted on the roof only sticks out above the roof when there is a chimney stack. In this case, the antenna should not stick out more than 60 centimetres above the highest part of the roof or above the highest part of the chimney stack, whichever is lower.

Where do I mount my CB antenna?

Does a Firestik CB antenna need to be grounded?

Q How important is it to have the antenna mount grounded to the vehicle? A Unless you are using a no-ground plane system, it is extremely important. Ungrounded mounts will usually cause SWR to be high across all channels.

Does ground plane affect reception?

It is worth noting that a poor ground plane or radiating surface may not affect radio reception. You may still receive transmissions from other radios with or without a ground plane. Basically, you can receive transmissions on a clothes hanger!

Is aluminum a good ground plane for CB antenna?

aluminum makes a fine ground plane and you dont have to be attached directly too it.. my antenna is mounted to an isolated aluminum rack over an aluminum roof, I didnt do anything else and it has great coverage.. try it first, then work from there.

Is it OK to coil coaxial cable?

There’s nothing inherently wrong with “looping up” extra coaxial cable. In fact, a neatly wound coil of coax can function as an air-core choke balun (“ugly balun”) which is useful for some antenna systems when located at the feed point of the antenna.

How high can I place an antenna in my house?

an antenna mounted on the roof only sticks out above the roof when there is a chimney-stack. In this case, the antenna should not stick out more than 60 centimetres above the highest part of the roof, or above the highest part of the chimney stack, whichever is lower.

How tall can my antenna mast be?
