"F" Connectors ?
"Robert11" wrote in message
. .. Hello, Would appreciate your opinions on the use of "F" connectors on coax between areceiving antenna and scanna. e.g., "F" O.K., or stick to BNC's ? The Daiwa coax switch box has in their specs usable to only 600 MHZ Anyone using for the 800 MHZ range, or beyond ? Thanks, B. I use RG-6 from 500khz all the way up to 1.2ghz and most of the time I'm transmitting. Works awsome for scanners and great for transceivers. I know you're saying that radio coax is 50 ohm and RG6 is 75 ohm but, I read an article, and I wish I could remember where it is, the guy that wrote the article said that if don't try to load a long wire with it, it works great. You have to use it for the exact frequency you plan to talk on. Now with the dualband antenna I'm using it for, and since I'm only transmitting on one freq at a time, it works just fine. I checked the VSWR on all my transmitting antennas and it's between 1.0 - 1.5 I love using this cable because it's smaller, you can put more of them thru the same hole that you can only put one piece of the other stuff and it's cheaper. I either put "F" connectors on the ends and then use adapters to go from "F" to whatever connector that is on the back of the unit I'm using or, I put on a PL259 and then use an adapter. Either way, it works just fine. If you're going to use a PL259 you need to be careful because the 259 whole alone is bigger then the RG6 so you have to get a reducer that goes over the RG6 so it fits snug. Also, I found out by accident that there are two different sized reducers and many sizes of RG6. I just happen to have 3 differenct sizes of outside jacketed cable so I had to take a piece with me to the local radio shack and buy the correct reducers (very expensive here) for the cable I had the most of. Then I went on ebay and bought 10 at a time for almost the price I paid for two at rat shack. I hope this gives you an idea of using RG6 for almost any type of communications application. Sorry for being long winded. -- Posted via a free Usenet account from http://www.teranews.com |
