IONOSPHERE ALIGMENT

If not have a LOS 100% free. It´s possible the aligment with using a method of Inosphere aligment. The theory of RF Basics, say´s its possible.

Any persons testing this metod with canopy BH10 or other canopy products ?

If you meant Ionosphere, then NO it is not possible to use the ionosphere. AT the frequencies that Canopy operates there is not ionsphereic reflection. In other words there is not skip. :wink:

Out of curiosity what is the frequency and output requirements to use Ionosphere alignment?

You are talking about HF radio. Shortwave Broadcsting, Ham Radio, Air Traffic, Utility stations. Anywhere from around the broadcast band (AM Radio) to about 30 Mhz, From about 22 Mhz on up useability depends upon Sunspot cylce and other factors. Useability is also affected by time of day i.e. where the sun is and is not shining among other things. As for power you will find people using milliwatts to megawatts on these bands :D

Another thing to note bandwidth is also limited because at those frequencies, the kind if bandwidth used by say a Canopy transmitter would cover most of the SW braodcast band for a single channel. :shock: and wipe out countless stations. That is because a channel width if say 5 Mhx is a much larger pervcentage of 20 Mhz than it is of 5 Ghz..

:D

Weren’t there some ham radio guys trying to bounce a signal off the moon a while back? You’d have to make sure no one wanted network access during the day… :lol:

Quite true, hams have been doing this for years. EME is an ongoing aspect of ham radio. :D I have a friend that does it. It also requires large amounts of power, computer software and custom made radio gear. My friend has a 20ft dish e.g. and the ability to rotate it in order to track the moon as it moves in the sky. But it is NOT inospheric in nature, in fact the frequencies used are deliberately chosen to be ABOVE those that support ionospheric propagation to minimize it's influence. You gotta get the signal to the moon first !! ;) Definitely a long range LOS operation, with a HUGE path loss !!

:D

Use an anetnna with enough gain and a transmitter with enough power and you can get signal anywhere…
