Hi in a Yaesu FT-301 http://www.radiomanual.info/schemi/YAESU_HF/FT-301D_user.pdf I need to connect a separate antenna on receive and a separate on transmit.
I have only a coaxial going up on the roof, so I can only use a phantom power (power through the same coaxial as the signal).
For the purpose, I have to use an external DC blocking capacitor at the transceiver side, because there is no DC blocking capacitor internal to the machine.
Now my question is what kind of series DC blocking capacitor should I use, based on the fact that it has to allow about 1-30MHz to pass through both on RX and TX and the TX is 100W of RF power?
Shall I use these silver mica (500v rated) ones or do I need bigger ones?
Any suggestions are welcome.
