To ground the antenna you want to put a ground rod in the ground and use a copper braid strap between the antenna and the ground rod. Make sure no gas pipes or lines are in the area you are driving that ground rod into the ground. Put a couple round circles in the coax in a couple places too and make sure they stay. This will stop lightning from traveling into your home should there be a strike. You need to match that antenna to your radio. You want to hook an SWR/watt meter in line with your radio to get the best consistent reading. If you get a stronger signal with your CB on lower channels then I'm led to belive your antenna is to long. You really should put an SWR/watt meter in line to be sure of the SWR. If the SWR on channel 40 is higher than that on channel 1, your antenna is too long. If the SWR on channel 1 is higher than that on channel 40, your antenna is too short. Adjust the tuning coils according to your findings.

Glad I could help. If you have any more questions, feel free to ask.
just moved my homebase airiel out of the loft cavity on to side of house on a steel pole but now ive tryed it when i key the mike i get very little signal movement have i extended the airiel by adding the steel pole
How many green bars light up when you key down on the mic? Do you have a meter inline to check your SWR? What antenna are you using? So we can figure out if you need to address the tuning coils of tune it another way. Putting your antenna in the air will get you a better signal because AM travels line of sight. Unless it has db gain to it the antenna does not add power to the signal. Make sure if you are using a metal antenna that no metal is touching the pole from the antenna. Have you obtained a signal report at all? If so what was it? If you had such a varying signal from one side of the band to the other and have not put an SWR meter in line to match the antenna to the radio it is possible your radio has suffered heat damage. One indicator would be 1 light or none on the meter on your CB.

hi the uniace300 has a built in anologe needle and when i hadent insulated the pole was only going up to one but now ive redone it and insulated with insulation tape and shotened the pole a inch or 2 and added a earth cable iam all good adding a zetagi b300p amp now i live at a vally mouth near some foothills any tips for me iam using a thunderpole i think top is up about 40'
soz just checked ebay its a VENOM Homebase high gain CB radio antenna aerial new 1/2 wave
In the United States, FCC rules govern the height of CB antennas. The antenna is legal if it complies with either of the following rules:
1. It is no more than 60 feet above the ground, OR
2. It is no more than 20 feet above the top of the tree or building to which it is mounted.
So get the antenna as high up as you legally can. A bad antenna up high will in fact outperform a good antenna down low. If you can run your coax cable for a distance and get your antenna on a hill or get the base of the antenna at a higher level you will be doing your CB a great service. If you do this then I recommended running the coax through PVC pipe to help keep the critters from nibbling your coax. Where the coax goes into your antenna you want to take your coax and run 5 circles about 5 inches or so in diameter and tape it so it remains that way. Lightning will not travel in a circle. This will help stop lighting from travelling to your CB and possibly you. I recommend RG213U coax or RG8. Some people will attempt to argue the 3' "rule" to the length of your coax. Just make it the length you need.Insulate all connectors with electrical grease and electrical tape. Make sure to mast that antenna. If you strap it to a tree I use movers straps that ratchet to ensure a non loosening grip. Glad you got your set up going. If you have any other questions. Feel free to ask.
