To match the Raydel's idea of the Cuban's Satellite setup...
I have write an article in my blog with some pictures of my satellite
In short (more description and pictures on the blog)
- 70 cm channelized Kenwood TK860
- 2m Alinco DR-130T with subtone module...
- 2m Jpole at 12 meters from the ground with 30m of Heliax LDF-4 50 Ohms
- 2m DK6ZB kind 28 ohms Yagui with 3 elements (~9 dBi) homebrewed in an
Arrow style with the 70cm yagui in building process...
- 70cm 6 element DK7ZD kind yagui for 70cm (~17dBi)
I use a PC headset with phones and mic, the mic is for the 2m Alinco and
the phones for the kenwood...

Sometimes I use better antennas (an arrow or a 70cm yagi, 2m 5/8 vertical) while operating portable, but when transporting a yagi or an arrow antenna is difficult I use this low efficient but yet capable light weight system that fits on my backpack.
