Yes, but not very effectively. VHF and CB radios are on different frequencies and therefore for best efficiency require different length antennas. You might be able to receive with the CB antenna, but transmitting will result in a high SWR and possibly overheat, shutdown, or destroy your VHF radio.
Some of the ham (amature) radio frequencies are in the VHF range (2 Meters) and require short length antennas. There are other allocated ham radio frequencies called HF that use considerably different (longer) antennas. VHF antennas (in inches) are short and HF antennas are longer (several feet) because of the wave length or frequency. For the antenna to be effective it must be resonate at the operating frquency. The resonant theory can be compared to the short strings on a violin being higher audio frequency and strings being lower in audio frequency. Simply said one must have the proper resonant antenna for the frequency to operate properly. Listening to VHF the antenna theory still applies but not critical as transmitting. One can listen with any antenna length but it may not work as well because it is not "tuned" thus limiting its sensitivity or performance.
The reason you have the high SWR is because the antenna is designed for frequencies
that are very different from what the CB radio is putting out.
There are ways to add lumped components (coils, capacitors) to the antenna, to "tune"
it to frequencies that it's not cut for. But it's a complicated process, and when you're
done, the efficiency of the tuned antenna can be quite low. By far your best bet is to
start out with an antenna designed for CB frequencies.
VHF is the radio range of 30 to 300 MHz. CB radio falls into HF (High Frequency), with all frequencies used being under 30 MHz. Frequencies under 30 MHz will hit the ionosphere and bounce back to Earth - this is called skip or DX. Frequencies over 30 MHz typically penetrate through the ionosphere, causing a line-of-sight limitation.
So long as you have the right coax length and whip, and get your SWR tuning done properly, yes.
No. The old Citizen's Band (CB) consists of several skinny channels between 27 and 28 MHz, and that's where the receiver part of a CB transceiver operates. "VHF" is technically the range of frequencies between 30 and 300 MHz.

VHF is in the range 30 to 300 MHz.
VHF radios work by the line of sight principle
There are many places where one can learn to talk on a CB radio. One can learn to talk on a CB radio at popular on the web sources such as Jalopnik and Ipadventures.
No, they cannot.

history of vhf radio
You need a VHF radio antenna, a VHF radio receiver and of course a station broadcasting on the VHF frequency.
A mobile CB radio.
The CB antenna is made for a limited band of frequencies and the VHF is a wide band antenna made for higher freqs. A CB antenna will not make a good tv antenna. A CB ant. is mounted on the vertical and tv ants. are mounted horiz. in the USA. VHF antennas are much smaller as they are for higher frequencies. Usually, they have many elements (rods) and will go from long in the back to short in the front. Certain CB antennas (beams) are mounted horizontally, but all of the elements are roughly the same length - and about twice as long as a VHF antenna. The elements on a horizontal CB antenna are roughly 18 feet from end to end.
The PRC77 radio operates on 30.000 to 75.95 MHz. If the Harris radio operates on any of the same frequencies (I know you said it's VHF, but VHF covers 30 to 300 MHz), then it can.
VHF is in the range 30 to 300 MHz.
Because VHF signals have a line of sight limitation.
I do not see how a CB radio could interfere with VoIP service. If the CB radio is creating interference on the line, check your telephone. Or even check your broadband modem to ensure that you are not creating packet loss due to the CB radio.
To install a Cobra CB radio in a 2010 Chevy Lumina, first disconnect the battery cables. Then mount the CB box and then power the CB radio. Then mount the antennae.
