BD7PRI Connect one side of the coil to one oscillator and the other side to the other oscillator. Run a coaxial cable out from the coil, with several turns, and it will be okay.
BH5UNT 我自己琢磨出的方案,不需要焊接,牢固美观,方便拆换。重点是那个免焊BNC头,利用螺丝来紧固导体(白色的一小截电线) 我用万用表测过,这个BNC头的两个端子实际上,是分别和外导体 及 馈线芯相连。这样就能够免去剥线、引出屏蔽网做平衡转换的麻烦
BG7RCA BH5UNT Got it. Got it. The solution is to use an adapter to avoid cutting the wires. (But I want to cut one coaxial cable in half and use both as two separate cables)
bd4unw I simply press on one terminal, without needing to solder, which makes it easy to disassemble.
bd4unw BG7RCA I am using M3 size round crimp connectors. The cable I'm using is RG316, which can be purchased with pre-stripped cables from TB Jinli Sheng Electronics. You should also purchase the crimping tool and stripper separately if needed. I bought one that works with a regular pair of pliers.
BH7JUO Assuming no losses, what's the most convenient way to connect them? But if we consider losses...
Bi4KKF It's a simple DP antenna. You connect segments to the outer and inner conductors, plus a reflector and waveguide, and that's all you need.
BI1NIZ What is the impedance of your Yagi antenna? Is it 12.5, 18, 28, or 50 ohms? If it's not 50 ohms, you will need to use an impedance matching network. If it is 50 ohms, the correct approach is to use a balanced transmission line and then process the common-mode current, for example: For example: The principle is this:
