Low Noise Amplifiers
It is impossible. We simply take a lot of old ideas and put them into a sort of mental kaleidoscope. We give them a turn and they make new and curious combinations.

TR1296H-28 transverter
LFA Mhz 11 elements antenna. Send us you obsolete products and will make an evaluation, days is the average time to evaluate, after that, immediate payment! Time Owned: 6 to 12 months. Due to the waterproof housing and the attached mounting clamp, the LNA is perfectly suitable for mounting it directly on the mast and close to the antenna.
Spare parts for HP Step Attenuators
It provide the first amplification of the RF signal coming out from feed horn. Herebelow there is a comparison between some LNA available complete and tested or in kit, at reasonable prices:. It is the cheapest solution with excellent performances. I can provide the Dubus article that describe the preamplifier to everyone who decide to build it. Obtained the full kit, that is designed for the amateur band of MHz, it is very easy to retune it for hydrogen line : it is sufficient to decrease the inductance value of the wire loop L1 , in the input circuit: 33 mm long instead of original 36 mm. After this simple modification we was able to obtain a gain of 17dB and a noise figure of 0.

Microwave EME
Equipment on 9cm: - A homebrew transverter based on the Zac Lau no tune design is used as the basis of the system. This provides a low level output to the PA. A 2nd LO has been built with appropriate switching to allow Rx in the Mhz band. Dish Feed:. The dish feed is a square septum feed with a transition to a round septum and a choke flange to improve dish illumination. The feed was built out of 0.

I was also QRV when travelling. First in on Jersey Island, than in on Crete and finally in from Island of Elba, see below. To make sure if it will fit I made some calculations which you may check here. I still had to construct the support for the feed enclosure, but this was easily done.
