Does feed line length matter?

I buy coax, cut it to the length I need, add the connectors, check the SWR and talk and I am ham and I don't give a crap about connector loss and never will. Lock this thread...
I did that once, made a mistake while putting the connector on, needed a cable stretcher. Now, length needed + about 2'
I normally operate QRP while doing portable so an loss is cumulative, connectors are not on my radar at all.
 
Look at Andy's profile. He apparently banned himself.

Previously he had a statement that he would be away for several weeks and would not be available. Apparently on another site he used to disappear for weeks at a time then return and be confrontational. Too bad. He really did have some good things to contribute.
 
OMG!

The issue of Resonance and Radiators - and the Feedpoint impedance are variables that many CB'ers or Amateurs as shown above...tend to ignored because people are too focused on SWR.

The only SWR I focus on is what is present on the feed line and at the antenna socket to minimise losses on the transmission line and to stop the transceiver from blowing its nuts apart. I don't give a toss what the feed point impedance and therefore SWR is of the antenna is in relation to 50 ohms because as long as you can match it to what the transceiver needs it doesn't matter. One of my best contest antennas I used multi band had a SWR at the feed point of around 85:1 according to antenna modelling. SGC 230 antenna coupler between the feed point and the coax to the radio kept everything happy and a lovely strong signal booming out from it.

Connectors don't matter because they should be manufactured to be a 50 Ohm impedance (remember how impedance is calculated as a ratio between the outer diameter of the inner conductor and the inner diameter of the outer conductor) and therefore insertion loss of a properly built to spec connector with coax properly installed in it, which a lot of people don't do in respect to braid and PL259 connectors, then losses are negligible. Use an Amphenol 83-SP1 preparing the coax as per their instructions and you should have an almost perfect 50 Ohm impedance through the connector.
 
The only SWR I focus on is what is present on the feed line and at the antenna socket to minimise losses on the transmission line and to stop the transceiver from blowing its nuts apart.

you might want to rethink that. Reflected watts affect the source of the signal. the end result is the heat generated at the source component in which they will eventually fail do to being operated out of spec.

    7300 very nice radio, what's to hack?
