The Friis path loss is only about 146 dBm at that range. So, raising the stations to about 95 miles high at each end does give you a much more auspicious start, link-budget-wise — if you spend enough on …

How to determine the minimum distance between ham and TV antennas

WebThis frequency will allow you to establish a secure reliable connection between your two locations when you do not have clear, unobstructed line of sight. Please note, that maximum distance is typically restricted to 1/4 mile or less when 100% trees are in the way. The most popular 900 MHz point to point package is the GNS-1138HP. The lower ... WebFor 1 GHz it is proportionately smaller. In other words, if an antenna is placed at least 1.6 m away from the radiating source (say at 3 m), and we measure the field at that point, we can then use inverse linear distance extrapolation to predict the field amplitude at any other (further) distance — say 10 m, 30 m, and so on. jeong jun-ho https://mayaraguimaraes.com

If the Earth were a perfect sphere without an atmosphere, the radio horizon would be a circle. The radio horizon of the transmitting and receiving antennas can be added together to increase the effective communication range. WebIn telecommunication, the free-space path loss (FSPL) (also known as Free Space Loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air).
