http://lna4hf.blogspot.com/2014/01/lna4hf-is-ready.html
LNA for HF SDR Upconverters. Thursday, January 9, 2014. Finally the LNA4HF is ready after the holidays break. After the initial shipment we have the firsts batch ready for delivery. The final result is the pre-amplifier for the HF frequencies covering the range from 150khz to 30MHz. The high cut off frequency limitation is due to 5 pole low pass filter at the input. There is the possibility to remove the filter and use the pre-amplifier up to 2GHz. DC power supply: 6-9 V. Consumption : 18 mA. NF : 1-2 dB.

LNA for all: LNA + DVB-T = FAQ
http://lna4all.blogspot.com/2014/08/lna-dvb-t-faq.html
Low Noise Amplifier for many applications from 14MHz to 2500MHz. Friday, December 11, 2015. LNA DVB-T = FAQ.

Should I position the LNA close to the antenna? I've heard that I can power supply remotely my LNA using the Phantom power and Bias-T, is it true? The remote (close to the antenna) LNA may be power supplied using the coaxial cable, the same one t...

LNA for all: DIY Bias-T
http://lna4all.blogspot.com/2014/11/diy-bias-t.html
Low Noise Amplifier for many applications from 14MHz to 2500MHz. Thursday, December 10, 2015. I am receiving more and more requests for the separate Bias-T unit that can be accompanied with the LNA4ALL. The LNA4ALL has the Bias-T powering option but if you do not have such a possibility on your receiver side you need to buy one or to build one. Hack-RF, FCD, AirSpy support the DC over the coaxial cable but the cheap DVB-T dongles are without such an option. What about the RF power? You should not have th...
