![]() ![]() It gets another 2x messages per second than even the cantenna at my location. I can’t recommend the J-pole enough though. The cantenna is dead easy to build, and gets about 4x the messages per second that those junk rubber duck ones do. spectacular range (I now consistently get 200nm+, and my messages per second were double what I got from the cantenna.not quite as easy to build (I ordered some semirigid coax off amazon).good range (I get over 150nm consistently, and 200+ occasionally with it in a second story window, and many obstructions around.cantenna: Advice for my Cantenna setup w/ outdoor enclosure.I have made and tested quite a few, but two designs have stood out far above the rest. dBm to Watt converter Stripline Impedance calculator Microstrip line impedance Antenna G/T Noise temp.I also bought those, and found that they had far worse reception than my home built antennas. Effective sizes include: 149. A cantenna may be optimized by using a can with the right measurements. The longer the better and An N-Female chassis mount connector, available at many electronic supply stores. Following equation or formula is used for parabolic antenna gain calculator.įollowing is the list of useful converters and calculators. A tin can roughly 8 cm (3.15 inches) in diameter, such as a Pringles canister. If needed, what value of attenuators we need to incorporate forĮfficient link operation. Whether the attenuator pads are needed or not. It also helps to determine, at the receiver how much power will be available to reproduce the transmitted information and It helps to determine as to how much power we need to generate using RF Transmitter part bearing into It is very useful in RF system link budget calculation and analysis. Output Gain (dBi) = 47 Antenna Gain Calculator EquationĪntenna Gain is the measure of amount of boost provided to the input sigal by theĪntenna. The gain of parabolic antenna type is calculated by antenna gain calculator.Īntenna frequency in GHz (Input#3) : OUTPUT This page of converters and calculators section covers Antenna Gain calculator. ![]()
