cb radio antenna legal height

[Zibi 01]

CB-Radio working on eleven Meters Band it means the correct place must be on eleven meters poole.Why? Because 11 meters band antenna must be 11 fitted on 11 meters poole for Full Wave range. You can of course installed your antenna on 5-6 meters poole from ground.But it never give it full specification for work. In Poland minimum poole is eleven metrs from ground.Maximum sometimes 35 meters up from the ground.Antenna will be working also one meter from the ground ,question is how? On 11 meters up from ground antenna have full wave and working excelent from 26 to 28 MHz.Of course You still need calibrate SWR obviously it is urgent must be done!!!

Thanks for sharing this useful information here. most of the time i have to design the antenna for many applications.
According to Google Earth, the nearest runway to me is at an alt of 25m and my place an alt of 26m and I'm 2.06 miles due north of runway Heathrow's runway 09R. Would this affect me? No planes fly low enough around this area and are usually going around my location.

Stick it up and tell them it's an antique tv mast as you are watching 1920s tv.

Zibi 01 after reading your comments on the use of a full wave 11m antenna and the need to place the antenna 11m high with a full wave being 11m or 34'. I can see your logic in what you say, but there are a number or issues to take into consideration here. I take it from what you are saying you are running a full wave diapole antenna @ 11m, it is actually more beneficial to run a 1/2 wave or 1/4 wave antenna than a full wave.
It is all to do with the shape of the signal you are transmitting, with a full wave antenna the signal shape is going more or less straight up, which is great if you want to talk to the space station. We are looking to squash the shape down so if you looked from the side it would be more donut shaped. This is achived with a 1/2 or 1/4 wave antenna and some kind of ground plans.
Also the height is not such a big issue, for example l have friends who cannot put up antenna due to housing rules, who use a 11m magnetic loop antenna in the loft or on the window sill and still talk to people in europe as well as there friends in the Uk.

Enjoy your radio, 73 Dennis

These days I have a walkie talkie with its own rubber duck type antenna, and a PSU operated base station which I attach an indoor mag mount type antenna to. I used to have (when domiciled elsewhere) an external WOT Pole attached to our bungalow at about 8-10 feet from the ground. This worked quite well. The old CB Radio Licence had aerial height stipulations relating to transmitted power and attenuation requirements. I don't know whether Ofcom still stipulates this.

I feel for you Billy the Kid Authority`s are just a pain & just like complaining about anything & probably everything grumpy buggers if the Antenna is out of the way & doing no harm to anybody then there`s no need for anybody to complain about it might as well stick a tank whip onto chimney & then watch & wait to see who complains

Hi can anyone tell me the legal height on a van please.

[SideSide]

Hi can anyone tell me the legal height on a van please.

Articulated trucks. These can be incredibly tall. I take my logic from there. My Sirio 3000 antenna whip is just over 180cm, my small van is around the same height. I don't have any problems at all. I have a mate that has a full sized Transit van, and he has the same antenna, and he doesn't have any problems. The only inconveniences are height restriction barriers, and multi-story carparks.
I would say there isn't a "legal" height as such, but as with all these things, common sense is a big player.
Just out of interest, what van do you have, and what antenna are you using?
I hope this waffle made sense.

All the best,
Chris.

Safe height on a level crossing with overhead wires is 16', your rig won't appreciate 25kV up it's chuff.
I've run high top Sprinters with K40 and similar types on the roof for years. The biggest risk of damage or destruction is low tree branches - done it many times.

it will vary from one local authority to another , but having just checked with North Ayrshire Council , the general rule for aerials without planning permission is not more than one metre higher than the roofline .

I'm taking that to the the Apex of the roof , so my new Thunderpole 5 is going on the rear wall of my home ( so it can't be seen from the street ) and mounted with its base just above the gutter ( alas plastic on my house or I'd ground the antenna base to the gutter for good measure ) , and my Blake 8 element Band II FM aerial for my hi-fi is going on its rotator on the gable end of the house with the rotator level with the apex and on a 1 metre mast to comply with the council regulations . I'm not going up on the roof or the TV aerial left by previous owner would be coming down ; however the satellite dish on the front of the house will be coming down as my house is a TV free zone .

Was always commonplace to see 'big rigs' with things like Firesticks on mirror mounts - they must have reached quite high , biggest mobile antenna I ever had was a thing called a Bullwhip which had a base loading coil about 2 ft long then a whip which must have been four or five feet ; that was mounted on my rear bumper . These days I run a K40 on the roof of my Mercedes W124 estate , with the mount fitted into the roof just far enough forward to allow the tailgate to open - looks neat and works well with my Audioline PT 342

hi all,

ok i know that there are people who are not sure how high there antenna should go Legally but i did manage to stumble across the following,

Part 95 - Subpart D - Rules for CB Service
Citizens Band (CB) Radio Service

{A} "Antenna" means the radiating system (for transmitting, receiving or both) and the structure holding it up (tower, pole or mast). It also means everything else attached to the radiating system and the structure.

{B} If your antenna is mounted on a hand-held portable unit, none of the following limitations apply;

{C} If your antenna is installed at a fixed location (whether receiving, transmitting or both) it must comply with EITHER one of the following:

[1] The highest point must not be more than 20 feet (6.10 meters) higher than the highest point of the building or tree on which it is mounted or

[2] The highest point must not be more than 60 feet (18.3 meters) above the ground.

{D} If your CB station is located near an airport, and if your antenna structure is more than 20 feet (6.10 meters) high,
you may have to obey additional restrictions. The highest point of your antenna must not exceed 39.37 inches
(1 meter) above the airport elevation for every 109.36 yards (100 meters, 1 hectometer) of distance from the nearest point of the nearest airport runway. Differences in ground elevation between your antenna and the airport runway may complicate this formula. If your CB station is near an airport, you may contact the nearest FCC field office for a worksheet to help you figure the maximum allowable height for your antenna

[FONT=Times New Roman]

Local code is typically 35 feet [10.7 meters] in few cities it 40 feet max unless your on a ranch max high st by FCC is 60 feet [18.3 meters]. If tall buildings or trees is 20 feet higher. HAM operators likes tall trees and will have a tree timer installe the antenna.

11-meter business like using monopole or j-pole on top buildings.

A 35 foot monopole or j-pole from most homes will get 15 to 50 miles depending on weather and if lot of tall buildings. With other vehicle using a 102 inch antenna.
This data is from 1960's when only had 3½ watts today we have 4 watts at the Antenna.

Good luck
Dave
