Not quite the bandwidth advertised, but still not too bad...Bought it to make an active HF loop antenna for my SDR. Not sure what the noise level is like yet. Seems good for the price.
A little but powerful radio signal preamp, I use it for a 15Mhz-2Ghz scanner
As described.
Good quality amplifier. Radio stations are stronger 3-5dB, NOAA images are very longer and less noisier now. The ADBS signal increased the range from 250km to 350km.
Excellent for experimenting with QRP and SDR radios. Iused it for a broadband preamp together with homebrew filters. Great value for money.
Working as expected currently using it to monitor ADS-B on 1090Mhz.
Брал для эксперимента на самодельную ТВ антену DTB2 результат на лицо. С 25% уровня сигнала на 700 МГц поднялось до 95%. Не ожидал но факт. Так что рекомендую по крайней мере на цифровое ТВ подходит😇 Ещё пару слов об упаковке очень охрени.... .. хорошо. Смотрим фото.
wszystko ok nawet przed uzgodnionym terminem
very good , works as it should
I have received product November 6, 2021. Product not yet tested. I require cables for Input ad Output. Each should be 5 meters long with BNC connectors for other circuitry. Many thanks for prompt reply
