Is There A Correct Daisy Chain of Equipment?

[TwentyTwo-Zero]

Yesterday I was talking with a (local) radio enthusiast about equipment. When I mentioned how I have my equipment set up he freaked out and said I had it all wrong. Sooo...

Is there a "correct" way to set up your equipment as far as what comes first, second, etc? Right now I have a jumper running from my radio (rci 2995dx) to a tvi filter (bencher ya-1), from the filter to my swr/watt meter (dosy tc-4001-p) and from there to my antenna (shakespeare abs1600). I was told I should put the tvi filter after the swr/watt meter instead of at the radio output, and that the filter would throw off my swr. I took a reading from radio to antenna, then put the filter back inline (between the radio & meter) and saw no change in my swr. It seems to me that you would want the filter at the radio output so the tvi would be trapped at that point and not travel through the jumpers & swr/watt meter. Does it really matter where the filter is located, or is this guy suffering from overexposure to rf?

Comments/Suggestions?

your equipment is assembled correctly . you never want anything but coax between your meter and your antenna . IF you were to get an amp you would want it between your radio and your filter assuming your filter can handle to power of the amp if it cant you need a filter than can handle to power adequately . you should tell your friend about this forum .

Hooking Up The Meter

Your SWR meter needs to be connected into the coax between your radio and antenna. For this you will need your meter and a short jumper of coax with the correct connectors on it (usually PL-259s).

SWR meter hookup Connect one end of the jumper to the back of your radio. Now connect the other end to the "Transmitter" socket on the SWR meter. The antenna's coax now connects to the "Antenna" socket on the meter.

Make sure all connectors are well seated and done up snugly.

Most SWR meters will not be damaged if you get them backwards (I've done it more often than I care to admit) but they will not give you accurate readings as the forward and reflected functions will be reversed.

The operation of SWR meters varies a bit from model to model, so be sure to read the instructions for your meter carefully before proceeding.

I dunno...after sandbaggin' and listening to this guy for awhile I think he would be more the type to instigate an argument rather then try to help out. Besides, I don't want him to know where I've been getting my edgeamakayshun from...

Bart that an antenna tuner . hams use that for an antenna that wont tune into a band they're on or using 1 antenna to cover several different bands . in that particular special application it would go in between the swr meter and the antenna . for cb use the band is narrow enough and the antennas are designed for the cb channels without needing a device like that . thanks for pointing it out though .

actually I posted because the pic shows the low pass filter placement in relation to the swr meter...The original question was about whether the filter should be before or after the swr meter. Booty, look under the pic of the tuner and see the block diagram for what I'm saying.
