Cell phone antennas and a direct connection or a repeater?
The repeat antenna inside picks up the output from the cell phone and boosts it up to 3 watts and sends it to the antenna on the outside! Since the amplifier is controlled by the cell tower, it will power up your cellphone signal to keep you connected. Let's say you were getting dropped calls and if you were putting out 1,75 watts of power from your phone this would stop. But wait, your phone only puts out up to 0.6 watts! Well the amplifier would pick up your 0.6 watts, add another 1.15 watts to it for a total of 1.75 watts! Pretty cool huh? The nice thing about vehicle mounted antennas is you don't have to drill a hole in your trunk to put in one! Not anymore! 
This is the cell phone antenna I installed on my Mercedes Benz. Now I'm not about to drill any holes into my Mercedes Benz 300 D! I'm willing to bet you wouldn't either! This type of antenna mounts to the edge of the trunk lip and secures with 2 allen head screws. It's slim, safe and secure and it can be removed without leaving holes in your car!
Antennas, amplifiers and your home or office.A lot of people have told me that they would cut their land line if they had better service at home. Keeping your land line is not a bad idea because emergency services like 911 will know where to find you even if you forget your address! Yes, as silly as this sounds, it has happened. If your cell service at home is so weak that you have to go outside, like I used to, to make a call then you should have the amplifier and repeater installed in your home. There are special amplifiers made for this and they have a usable range of about 800 feet. A fixed location antenna works really well at home or any stationary building and my recommendation here is for a Yagi antenna. A Yagi is very effective and makes a good long term solution, especially for a remote location such as a mountain cabin! There are those who live off the grid completely and their electricity is supplied by photovoltaics (solar cells) and wind turbins! These provide enough electricity to feed large batteries to store enough to run the home computer, satellite dish and major appliances, including the cell phone, often the only form of communication! You can get a power inverter to convert battery power into 120 Volts AC to run the same appliances just like you do now! This is not as unusual as you would think! RV'ers have been doing this for years. Click here to see remote Yagi cell phone antennas! Marine applications and cell phone antennas.In this section we will deal with watercraft and your cell phone. This is very similar to systems in moving vehicles, but because water is involved, marine antennas must be used.Water, especially sea water will make metals rust and corrode really fast. Unprotected steel will not last long and you will have problems within a week! Marine antennas are made of stainless steel and brass and will be coated with fiberglass to withstand the effects of water damage. This is why you can use marine antennas on land, but not vice-versa. As with any application of electronics and water, keep these two as far apart as posible even if your electronics are rated for marine use. Water and electricity can be a deadly combination!
