Using a better antenna and coax, and having the SWR tuning properly done will increase your range. I'd recommend finding a reputable CB shop for your antenna, coax, and SWR tuning.
the frequency range of radio waves is ranging from 3kHz-300GHz
One way to increase the range of a walkie talkie is to increase the elevation of the set. Climbing a tree or a hill can increase the range significantly.
Researching to find the transmitting frequencies for Radio Tiempo has provided a wide range of results. It appears that there are a wide range of radio stations known as Radio Tiempo such as YVOZ, YSQJ, WNEL and WLZL. Due to the wide range of listings for a variety of Radio Tiempo listings it is impossible to provide a true transmitting frequency.
VHF is in the range 30 to 300 MHz.
The frequency range that the radio waves can penetrate the human body is between 1Hz and 10 KHz. This frequency of the radio waves is however not dangerous.
The range on an FM transmitter for a car radio is roughly designed to transmit a radio signal to more than 500 meters away in the FM broadcasting band.
The values of the range also tend to increase.
See page 101 of your study unit. In there you will find that radio frequencies used by commercial radio broadcasting stations range from about 550,000 Hz to 1,700,000 Hz.
USB radio transmitters usually transmit within the equivalent range of about 2 city blocks. Some higher end models transmit at a higher range than others.

The range of a Cobra CXT545 2 way radio is the same as that of a cell phone that reaches satellite for transmission purposes. The Cobra CXT545 2 way radio range can be extended with upgrades that are available by the manufacturers. But for the most part, the CXT545 2 way radio uses radio signals to the nearest radio tower or to the cell phone towers that are in abundance in today's modern day world of technology.
Not necessarily. While a higher wattage CB radio can potentially increase your range, the antenna plays a crucial role as well. An efficient antenna matched to your radio's output power and properly tuned can have a greater impact on range than just increasing the watts alone.
