can someone tell me will this amplifer let me listen to vhf and uhf frequencies by amplifying them. Channel, Cascaded Ultra-Low Noise Amplifier

Seeing how it states this...

1090MHz (ADSB) and 978MHz (UAT) Center Frequencies​

I would say the chances of it working on other frequencies are pretty slim.

Definitely the wrong animal for your VHF/UHF bands. And adding amplifiers can be tricky if you have nearby signals which may require filters. What ever you are told, it can turn out to be an experiment that may or may not be successful and may require your time to optimize or you may just turn out to be lucky. I use a Pre-am in the >$100 range and various filters.

Fist some back story i have been using a generic noolec LNA for awhile but it died it was rated from like 20 to 2000 mhz.it done fine but small. anyways i'm getting rady to buy a new one can u all look at these and tell me what i should get? and please done say the same one i had it was junk in my book. ALSO I LISTEN TO VHF and UHF and some 800mhz so these need to cover those; btween 150mhz to 450mhz

OK here goes up first

1 Nooelec SAWbird+ ADS-B: Premium, Dual-Channel, Cascaded Ultra-Low Noise Amplifier

2 LNA-VHF-B Pre-Amplifier

3 Tangxi amplifier

4 Oumij1 amplifier

5 Active RF Isolation Distributor it says this only goes to 150mhz but can be pushed o 300mhz but it still wouldn't sereve my purpose wuold it?

6 High Impedance Amplifier Impedance Conversion Device for SDR Walkie Talkie for HackRF for One Donut Antenna would this reach 150 to 450?

7 Signal Amplifier 100k-6GHz Full Band Low Noise 9037BAT-LNA RF Amplifier High Linearity Ultra-Low Noise Gain Block Amplifier now my fav but it's so cheap makes u think its junk but what do u all think?

8 High Impedance Amplifier Small Loop Antenna 1Hz-300MHz Doughnut Short Wave Antenna 5V 600mA for HackRF One for SDR Walkie Talkie also cheap but differnt in range

9 RF Amplifier High Flatness Amplifier 10M‑6GHz 20DB Gain LNA RF Drives Receiver Low Noise Amplifier for FM Radio then there is this one which looks pretty nice

10 Nooelec Lana - Ultra Low-Noise Amplifier then there is old faithful whch i have owned before i lasted 6 months and stopped working.



if any of u have any time at all could u please look at these amplifiers and tell me which one should i get to better hear my VHF and UHF and 800mhz? i mean thre is 10 of them here and i just want the best one that will give me the best performace and strongest signals. Thanks everyone..

and kevinC i i hope iposted this in the r

The amplifier I use (I have reasons) is a RF Bay LNA-1400but probably far more here use (and I sometimes use)a Mini-Circuits ZX60-P103LN+ or similar.

Good is not cheap.
