How far can a military radio transmit a signal without the help of a satellite?

Or do military radios not use satellite at all?How far can a military radio transmit a signal without the help of a satellite?It depends on the type of radio - the military uses a wide variety operating in different frequency ranges for different jobs.



A typical military HF radio can pretty much reach anywhere in the world. However, doing so takes a lot of hard work, calculating, skill, luck and patience. The typical whip antenna you see in movies won't hack it - an antenna capable of bouncing signals off the ionosphere and reaching and receiving across gargantuan distances will probably be a massive, oddly-shaped series of cables strung up across trees, buildings or clark masts. Said antenna needs to be "cut" to the length appropriate to the frequency used, pointed in a precise direction, given enough power and if weather permits it, you may be able to talk to Sweden (albeit usually distorted and crackly to some extent



VHF radios are the more widely used means, and have a much shorter range (around 8km with excellent weather, no trees or hills in the way and external power). Unlike HF, setting up their antennae is a snap (you can use a simple whip for most applications), it's easy to communicate while moving and transmissions usually have more clarity.How far can a military radio transmit a signal without the help of a satellite?
The military loves satellites. It allows them to communicate any distance. From to the guy on top of the next building to HQ on the other side of the world. However, if they couldn't use satellites for whatever reason, they'd fall back to the methods still used today as well as before communications satellites.



HF Communication. The frequencies below 30 MHz can be good for worldwide communications. The most efficient of these fall in the high frequency (HF) spectrum. Skywave propagation is used. These signals bounce off the ionosphere 250 mile above the Earth and come back down. These signals might bounce off the Earth back up to the ionosphere. This is called skip. Multiple skips will make it around the world. Different frequencies are better for this at different times of the day, year or even decade. This makes worldwide communication via HF an art and science.



Frequencies that are too high to bounce off the ionosphere rely on ground wave. These frequencies are more line of light plus some. Antenna height and type and power can send these signals 200 miles. This shortens as frequency increases until you get to satellite frequencies where you need literal line of sight with the satellite in order to work, look at satellite TV or your GPS receiver. You can extend the range of these very high frequency (VHF), ultra high frequency (UHF) and super high frequency (SHF) with repeaters.



You can use a combination of the above propagation and add Internet connectivity into the mix.How far can a military radio transmit a signal without the help of a satellite?Depends on the type of radio, what they are using to power it, whether it has amps, how big the antenna is, whether they have relay set up, the surrounding terrain, the time of day, the climate and weather. Higher levels of command and the Navy and Air Force are more likely to rely on satellites than, say, ground forces at the tactical level.



I think you should read up on radio propagation, it's pretty interesting stuff. You can pick up shortwave radio signals from thousands of miles away using a small handheld shortwave radio.How far can a military radio transmit a signal without the help of a satellite?
When I was in DC we would pick up skip from the Far East and sometimes Russia. RF (radio frequency) with the right conditions bounces off the ionosphere and back off the earth kind of like when you bounce a ball off the floor under a table.How far can a military radio transmit a signal without the help of a satellite?Several different types of radios/communications equipment used by various military branches for different nations. Each can and does transmit at different ranges. Be more specific if you want an honest answer next time.How far can a military radio transmit a signal without the help of a satellite?
there is a myriad of radios and things alike which the military uses
a radio wave , unobstructed will go on to infinity
