The material I chose to build the j-pole antenna was 3/4 inch copper pipe used for plumbing. Here are the plans to build a 2 meter J-pole antenna: The above dimensions for the J-pole are in inches. Measurements on overall length, and stub length are from the centerline of the separa...
With a matching antenna, the FM transmitter circuit shown here can transmit signals up to 2 kilometers. The transistor Q1 and Q2 forms a classic high sensitive preamplifier stage. The audio signal to be transmitted is coupled to the base of Q1 through capacitor C2. R1, R3, R4, R6, R5 ...
shape reflects virtually all of the light forward. Each light reflector is made of three 16×16-inch pieces of ¾-″ rigid foam insulation, and a 4×8-foot sheet will make six lights. The 16×16 pieces are simply taped together with 2″ packing tape. The fixtures are simple lamp ...

With an ohm meter check to make sure the wire near the old antenna PCB traces does not have continuity across either of the cuts made in step #1. Step 3: The Finished Product Your NRF24L01+ module will now perform far superior in what ever project you use them in. You can either enjoy...
After replacing CF3-4, VR1 should be realigned for correct signal meter readout.The antenna input balun should be disconnected if you only use the 75-ohm input. Such baluns often steal power enough to lower the sensitivity by 2 dB just by being connected in parallel with the input!

think .6v is very much but when you are talking in millivolt terms, it is 600 millivolts. The signal we are attempting to pick up produces one or two millivolts on the receiving antenna and if you need 600 millivolts to turn a diode ON, the field strength meter becomes very ...
