Business can sometimes mean company or firm. However, can it be used in the way company or firm are used?

For example, can I say:-


  
  "He is the CEO of the business."
  "It's a TV business."
  "A business dealing with drugs."
  



Question: Shortening the coax on UHF CB antenna caused SWR to get worse, why?
Answer: As long the antenna and the xmitter have the same impedance and they are connected with coax with same characterics impedance, then the length of coax has minimal impact on SWR.
You did measure the SWR before, now this means that from point you have measured it was a factor 1.3, this could mean that antenna was not tunned good and the cable itself was radiating acting like antenna, in sum the SWR was 1.3. Now you have cut of some piece of cable, normaly now it should perform better as the loss is smaller, but the whole impedance has now changed as the xmitter see. Therefore the antenna was never tuned properly, tune it.
