[Antennas] Change in coaz = change in SWR.

[Thomas Beltran]

I exchanged 100' feet of RG-58 with 100' of Cable X-Perts 1318FX.  After
checking the SWR with an RF-1, there is quite a difference - the resonant
frequency of the antenna has gone up around 600 khz.  For example, I had a
1.7:1 (checked just before changing the coax) at 14.230.  Now that freq
shows an SWR of  4:1.  The low point, 1.3:1, is at 14.880.  Before adjusting
the antenna, I thought I would check with the people on this list.  Any
ideas?  Tom W6EIJ
