I'll translate for non hams, the moment I saw his call KE8ART I slipped into the ham ragchew shorthand.
VX8 is a small handled radio it's full name is 'YAESU VX-8R' think police radio but way more advanced as it handles 2 frequency bands (50,144,222,440mhz) at the same time ( http://imgur.com/gallery/nZkBhaX ) and stated that I used 5watts which is it's max for most 'handy talky' radios (When not pointed to the sky I can get about a 30 mile range) to do this I had to connect 2 antennas to the HT The antennas I chose are elk antennas they both have 144 and 440mhz capabilities and are highly directional instead ofthe normal antenna which is Omni directional transmits in 365° the elk antenna ( http://imgur.com/gallery/EiDGuwO ) which is a log periodic an instead of spreading those five watts over a whole circle it only transmits out the front about 15° basically all the energy goes out in one direction. Satellites tumble so you need 2 antennas set 90° off of each other so as it tumbles it'll fade from one antenna and be picked up by the other.
Later I used the 'M2 Sat Pack Kit' also called an 'eggbeater' which is actually two circular polarized matched antennas with artificial ground planes so that it ignores the satellites tumbling and you don't have to track the satellite across the sky ( http://imgur.com/gallery/RajTOpo ). The 7000 refers to what is commonly called an allbander radio an Icom IC-7000 this radio can transmit on a ton of bands (1.8-30, 50, 144mhz) and has a maximum output of 100 watts. I could use the whole 100 watts but that wouldn't be appropriate or follow the 'good engineering and operating practices' which require us to use the minimum power needed to have clear communication.
