To find out how much loss to your FPV range, you can use my FPV range calculator. Removing/Changing SMA Connectors To replace the RP-SMA to SMA or vice versa on a video transmitter, simply cut off the bulk of the connector with some wire cutters or a dremel cutting wheel, and use ...
A normal G5RV system, including tuner, typically has about 1dB of loss on 80 meters and less than 2dB system loss (including loss from coax and matching) on 80,40, and 20 meters. People seem to hate G5RV's, yet they now seem to be willing to further shorten the G5RV and ...
Please refer to coplanar wave guide calculator in Appendix B for the calculation of width for Coplanar transmission line. The bandwidth (S11 ≤–10 dB) of the IFA is 220 MHz around 2.44 GHz, as shown in Figure 17. Figure 17. S11 of the IFA (Return Loss = -S11) Fi...
tested with a noise source and RTL-SDR are coax notch filters, aka coax stub filters. Coax stub filters are simply a length of coax, cut to 1/4 wavelength * velocity factor of the desired notch frequency. The required length can be calculatedusing a calculator, or by using ...
(coax). The SWR on the input side of the tuner may be 1:1 but on the output it is the same as it was without the tuner and losses the same. Since coax over 1.5:1 introduces too many losses,IT IS STRONGLY RECOMMENDED A 1:1 CURRENT BALUN IS INCLUDEDin these units especially if ...
Coax Cable roughly 5' in length or so (https://amzn.to/2LJcrij) A SDR Card/Adapter for your computer - I have this one from Amazon at ~$15 (https://amzn.to/34bgcU4) You'll need some adapters to connect the SDR to the Antenna. The card has a built in MCX female port. I ...
Because we're wiring a balanced antenna to an unbalanced cabel, the coax, you'll need a Balun (meaning balanced to unbalanced) to negate signalloss. To build it, just wrap the coax around the frame 4-5 times and hold it in place with zipties. In picture 1 of step 6 you can see ...
Calculated Ideal Components Values To better understand what type of the network is more useful, users can change component values to see how they will move the impedance on the chart (if the calculator supports this feature). Sometimes, the network can be sensitive to components values, so ...
