High Impedance Amplifier for SDR Walkie Talkie Small Loop Antenna HackRF One Donut Antenna
Product Description:
High-impedance amplifier is an impedance conversion device, which can convert higher impedance into standard 50 ohm output impedance, so as to play the role of impedance matching and isolation. High-impedance amplifier is mainly used for passive antenna receiving matching, suitable for sweet Donut Resonant Antenna, Whip Antenna, Whip Antenna, Magnetic Rod Antenna, etc. High-impedance amplifier, can be used in any radio receiver, radio SDR walkie-talkie, etc., Malachite, Small Loop Antenna, HackRF One, Donut antenna, Mini Loop, Radio Antenna , the tuning ring. And other models) higher input impedance can get as much energy from the input antenna as possible, reduce the signal energy loss caused by unstable input antenna impedance, and greatly improve the receiving performance. Since the impedance generated by the LC resonance is also very high, this amplifier can be directly connected to the LC resonant antenna to obtain energy directly from the resonant antenna, which can obtain higher gain and frequency selection characteristics. The LC resonant antenna includes the donut antenna. Magnetic Rod Antenna, etc.

Charges fast, works great, and the magnet is strong. The lifetime warranty is a huge bonus! If you’re looking for a reliable, high-quality charger with unbeatable warranty protection, this is the one to get! Highly recommend.
As advertised. Looks so classic and exactly as the good old days of transistor radios...the real transistor 😎 Size is big enough...see pictures. Sound is deep and full of base. Good reception of radio bands. Has Bluetooth and USB too but didn't try them yet. It captured our hearts my wife and I. Really recommend. Arrived before delivery date in a well packed package.
We love this radio and have it in our kitchen and it brings back nice memories. It’s simple to operate with dial tuning and the FM stations come in clear. The sound is also good and the look and quality is nice. Bluetooth device hook up is a breeze. We are very glad we purchased this radio.
Great portable antenna, especially when there isn't something to support a long wire. I've had this for a few months and wound up using this as my Field Day antenna (you can see it off to the right, behind my shelter in the photo below) and I got good results. It's quick and easy to set up, and very portable with it's nicely organized case. I've used this for POTA activations, and POTA hunting with great results.
This antenna works great, and great for the price, I'm pretty sure its the same antenna that HRO and DX engineering sell as "their" brand. The 20M and 40M tuning marks on the coil will get you pretty close to where you need to be with good SWR, you can also take the coil off and adjust the whip to work 17m, 15m 12m and 10m. I took the ground radio ribbon cable and split it into 5 sections of 2 strands and spread it out into a star strutcure I used this QRP CW at a state park in New York for about 2 hours and made 25 contacts several to the west coast and 2 DX contacts!
