[QUOTE="Terryl, post: 1093402, member: 369937"] Well a transceivers normal output inductance is 50 ohms, thus the need for 50 ohm cables and connectors, PL 259's and SO 239's are a standard for anything UHF and below frequency's, and can handle quite a bit of RF power. N connectors are good into the GHz range, and a good N to UHF adapter is a must if your converting over to any ham transceiver with a SO 239 input/output. If your just receiving then any type of connector or cable will work, but once you start transmitting your going to need to start using 50 ohm cable and connectors or you will have serious SWR problems. Now some older ham transmitters use 300 ohm ladder line, and a long wire, these type are a bit tricky to setup as the match must be balanced out on both sides. A transceiver with an internal auto tuner is almost a must now days, this keeps the finals from being stressed out and burning up. Now are you going to be using the discone antenna for receiving only? Or are you planning to use it for both TX and RX? Some discone's are RX only, the only one I know about that you can transmit on is the one from Diamond antennas, it can TX on most ham bands with out too much auto tune, it's all about the SWR on the transceiver, too high and your into a big repair bill. My Diamond discone has an N connector, I just used a UHF connector at the far end on the RG 213U coax into the radio, no need for any adapters that way. [/QUOTE]
