Space Range Antenna????????????????
anyone heard of this base antenna
A gun in the hand is better than a cop on the phone

Couldn't find it but i did find this.
The loop antenna is probably one of the oldest antennas in the history of physics and radio engineering. It was Hertz who first noticed that his "sparks" were transmitted through the air using small loop-like antennas spaced just a few feet apart! Since that beginning, magnetic loops have tended to take the back seat in the radio world,
Loop antennas have still perform well today and, even in some cases, outshone their electric-field counterparts? One big reason is performance! Loops can do just as well if not better than any other type of antenna! So if you have the space to set up a Half wave dipole why not consider a loop, and even if you don't have allot of extra space, you might consider the loop to be a very good alternative to the dipole.
What makes the loop different is that it creates a radiation field pattern that is the same as a dipole, but the field "lines" are magnetic, not electric. A radio wave is two fields, one electric and one magnetic, oscillating at 90 degrees to each other. A circulating flow of electrons, which produces the transmission pattern for a magnetic field, can radiate just as effectively as its electric field counterpart.
If you have the space, loop antennas are a great "buy" for the time and money invested in them, repaying your efforts many times over! Whether you hoist up the basic "Skywire," or go for that big DX vertical delta, diamond, or square; loops deliver!

Essentially that is true...but they aren't CBers. The space station has no radio equipment for CB. The conversations you've heard about are between astronauts who have their amateur radio license and amateur radio operators on the ground using VHF/UHF radios.Texas Mobil 219 wrote:I ve heard of some operators being able to chat with are space station.

Make me want to get my ticket. Good info Circuit Breaker.Circuit Breaker wrote:Essentially that is true...but they aren't CBers. The space station has no radio equipment for CB.
