Thanks to Zorro, JH1AJT, Champ, E21EIC and Franz, DJ9ZB to make possible that EAntenna be part of the crew of E31A, Eritrea in 2017 and 2018.
After a weeks of hard work finding a new plastic blocks material, EAntenna offers the most heavy duty plastic material in Amateur Radio antennas.
The HyperPlast(tm) have UV protection, and the temperature range is -170ºC to 240ºC, to offer the best value in products in all wheare situations; Desert, Sea, Ice, Windy situations, because the plastic blocks are solid piece, instead 2 pieces that can broke with heavy situations.
Choose EAntenna as one of the most important Amateur Radio antennas of the last 5 years

The EAntenna DUOSAT is a dual band antenna for VHF and UHF for communications via satellite. With only 800 grams of weight you can make all the low orbit satellites with an Handheld Portable Radior with the 5 Watts.
There are 3 LFA elements in VHF and 5 LFA elements in UHF, which guarantees a minimum noise level that is one of the characteristics of closed loop LFA antennas and a great bandwidth. And of course, the particularity that the LFA have 50 Ohms in the coaxial output, does not have any type of impedance adaptation that reduces the performance of the antenna
