## Why is the height of a VHF radio antenna?

Why is the height of a vhf radio antenna important? … The elevation (height above ground, particularly height above surrounding terrain, of a VHF radio antenna is a key issue in the area of communications because VHF radio is relatively line-of-site.

## At what height should install an antenna for a better signal?

A beam type of antenna at a height of 70 feet or more will provide greatly superior performance over the same antenna at 35 feet, all other factors being equal. A height of 120 feet or even higher will provide even more advantages for long-distance communications.

## How can I increase the range of my VHF radio?

Increasing the antenna height can also increase distance, so mount your antenna as high as possible, such as on top of your boat’s hardtop or radar arch. You can also get greater range with a longer antenna — it has a larger radiating element. Additionally, keep in mind that not all VHF radios are created equally.24 мая 2016 г.

## How do you calculate line of sight?

Substitute the above given values of Station1 and Station2 in the formula, = √ (2*height) = √ (2*250) = 22 Miles . = √ (2*height) = √ (2*350) = 26 Miles . Line of Sight = 22 + 26 = 48 Miles.

## What is line of sight communication?

Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves travel in a direct path from the source to the receiver. Electromagnetic transmission includes light emissions traveling in a straight line.

2. Place the antenna in or near a window. …
3. Go high. …
4. Test different antenna placements.

## Does aluminum foil boost antenna signal?

Wrapping aluminum foil around your antenna will basically increase the surface area and conductivity of the antenna to boost the signal that your TV receives from it.

## What direction should my antenna point?

To aim all of our antennas, face the front of the antenna in the direction the channels are broadcast from. You can find this information by going to TVFOOL. It will show you the compass orientation and direction the channels are broadcast from.

## How can I increase the range of my two way radio?

Three Tips for Extending Two Way Radio Range

1. Improve the antenna – Larger antennas can boost the range of a two way radio. …
2. Use a repeater – Signal repeaters can help extend range. …
3. Make sure your batteries are good – Low battery strength can impact the strength of your radio signal.

## How can I increase the range of my radio antenna?

Wrap the radio antenna in aluminum foil to bring the signal in better and move the radio in different areas of the room. Some areas may pick up the radio signal better. Move closer to the window, or a place where fewer obstructions will interfere with the signal.

## How far will a 5 watt VHF radio transmit?

With VHF and UHF, . 5 W will provide maximum achievable range in most conditions. That is because “maximum achievable range” is the horizon, which on average handheld-to-handheld is around 2 miles.

## Can I use VHF radio on land?

That’s illegal. Marine VHF radios, whether fixed or handheld, may not be used on land, period. It’s the law. Once a VHF radio goes ashore, it cannot be used for marine band transmission (without a Coast Station License).

## How far will a 25 Watt VHF radio transmit?

Under normal circumstances, as far as the horizon. In general terms this is around 30 miles from the point of transmission. However, the key considerations are the height and efficiency of the antenna. Higher means further.
