Wideband Active Small Magnetic Loop Antenna is very good antenna for SDR experiment, remote RX or as receiving antenna for rural high RF noise enviroment.
This preamplifier is based on famous LZ1AQ design.
I do recommend to read whole article here

Full finished SMD board.
I am offering you here the finished kit so you can now build this famous and magic antenna yourself. The construction is easy and straightforward.
The kit contains professionally designed, manufactured, soldered and tested printed circuit board with solder mask and service print.The PCB was designed and computer optimised for the best results, low noise figure and IMD performance.
In the KIT are only high-quality components.
Read all useful reading and surf the web for the applications.
The best reception can be achieved with the respect of recommended mounting of
the antenna and connection to the receiver. For the housing, I do recommend to use plastic box ora metal box with
the insulated penetration for the loop wires.
The board will fit in the BOPLA EM207LP IP65 box.
The preamplifier is power trough the coaxial bias tee, or via +12V pad at the board. It is up to you.
The bias tee should be placed in close to the receiver and through bias tee you will feed +12V/50-70mA DC power to the antenna. The antenna can be connected to the receiver via the coaxial cable, 75Ohm TV cable (well shielded) can be used too.
For the bias tee, the metal box is recommended. You can any small diecast box from Hammond for example.
See my other auctions. I always combine the shipping.
Important information and terms and conditions:
Even the postal services are about 99% reliable, sometimes could be something lost. I do recommend using signed and insured letter.
Yes, it costs more, but you can be sure, that you will get it or it can be fully refunded. I am sorry but I cannot be responsible for a normal
letter. I cannot manage worldwide postal services. I do always my best, but when I post your goods at the post office, my role is finished.
Do not write to me, where is my ..... I want to refund .... etc. I am an honest man and if you don’t believe, please use signed and insured.
Especially if you are from Russia, Middle and the Far East, Italy and sometimes from the UK too.
If you have selected economy shipping, without tracking. DO NOT OPEN THE CASE or ask for the refund! You took a risk and I cannot do anything.
I am giving you a possibility to get cheap shipping, but it is out of my control if it will be delivered or not.
During the last time, there are several cases from Italy and Germany as well. It will lead to the strict requirement for signed and insured shipping ONLY (= more expensive for you).
If you want to keep the low shipping fees in my auction, respect my rules, please.
DO NOT BELIEVE eBay's estimated delivery time!
eBay does not know Czech or Worldwide postal system well.
The delivery time is sometimes faster than proposed by eBay, but very often is slower (especially for overseas shipping and the UK included!!).
I am trying to do my best, in 90% I am shipping first working day after the purchase, but the delivery time is out of my control.
If you are in a hurry, use EMS shipping. Thank you for the understanding and cooperation.
