Base antenna installs (CB Radio)?

both antennas are poorly constructed - read that as JUNK.

There is a REASON WHY the FCC has set the maximum output power at 4W AM/A3 (12W PEP on SSB/A3J). If you really want to prevent "bleed over", do not exceed the LEGAL limit of 4W. 50 watts will increase the bleed over and 300 watts will wipe out the neighbors. A great way to endear yourself to the friends and neighbors.

A ground rod can help, it can also hurt. If you get a ground loop, it will cause interference across the band.

Yes, they make filters, it is called TVI filter. The TVI filter is a "low pass" filter.

"running power" is a quick way to draw the attention of the FCC. Also, the FCC has a toll free phone number for people to report interference. 1-888-Call FCC

I would not recommend those antennas.

"Bleed over" as CBers call it is properly known as splatter. That isn't always the problem with interfering with a neighbor's reception. There's a few different things that can be going on.

A good ground is always ideal.

The single best way to achieve success with CB is to use a precisely tuned antenna at good altitude, get it as high as possible, use premium cable, and have very clean audio with a relatively high average level (apparent loudness). With good audio and a great antenna system a 4Watt radio can cover 40 miles easily. A poorly designed or poorly tuned antenna is a sure fire way to cause interference.

Have the radio and any other gear professionally adjusted.

They're a little difficult to find for CB but you can get a low-pass filter for your antenna system which can dramatically reduce potential interference.

As for the power, thousands of people do it every day WITH interference.

You are worried about being a source of radio frequency interference (RFI) to your neighbors. The real reason why you are worried is because you KNOW it is illegal to operate more than 4 watts from a CB radio.

A ground rod and ground lead MIGHT help eliminate some RFI (but definitely not all) you might emit in your signal. However, when dealing with high RF power, it is a good idea to ground your radio and amplifier (which you obviously have) to protect against shock. Low impedance copper braid from each piece of equipment and attached (by hose clamp or such) to a 1/2 copper pipe acting as a RF grounding bus would be good. The pipe then connects to a piece of braid, as short as possible, to an eight foot copper ground rod outside. This might reduce any RF that might sneak back in to your radio and cause RFI.

You can get a low-pass* filter on your coax to make sure you don't radiate any harmonics. The biggest concern is that since your amplifier is illegal, it might be of questionable quality. It might put out spurious emissions. Monitoring your signal through an oscilloscope, spectrum analyzer or dialing around on a general communications receiver, especially on harmonics of CB channels would be a very good idea.

* CORRECTION: You would use a low-pass filter, not a high-pass to eleminate harmonics in your signal, oops!

Also watch your modulation, especially at high power. Overmod will create out-of-band interference.

OEM coatings are designed specifically for reception not reflection. Your best bet is to replace shaft only if screwed into base. You could try non-reflective rubber tape that's available at electronic supply store. The savings by paint isn't worth loss of signal quality....especially when you break down and need help. Good Luck !!
