roadrunnernm Posted January 24, 2015 Report Share Posted January 24, 2015 Hello All, Thanks in advance for your help and patience. On a homebuilt DIY antenna, is there any reason, other than ease of repair/maintenance, that a coax cable could not/should not be connected directly to the antenna? The point is to eliminate one connector (NMO, PL259 etc) and with it one possible point of failure. David Quote Link to comment Share on other sites More sharing options...
PastorGary Posted January 24, 2015 Report Share Posted January 24, 2015 What is the impedance of the antenna and how will that antenna connection point be matched to 50 ohm cable? Quote Link to comment Share on other sites More sharing options...
roadrunnernm Posted January 26, 2015 Author Report Share Posted January 26, 2015 For the sake of the general question, assume the antenna and the feed-line are both 50 ohms. (yes, unlikely, I know). Point being, does the connector have any function other than convenience ? I see some ladder-line antennas connected to the coax with only a choke made of 'turns of coax'.

deputycrawford Posted April 13, 2015 Report Share Posted April 13, 2015 I would set up some "N" connectors at each end of the feed line and have much less insertion loss. Jerry Quote Link to comment Share on other sites More sharing options...
zap Posted April 13, 2015 Report Share Posted April 13, 2015 What I would recommend using connectors. That way if you ever want to replace the feedline to something with less loss later on its easy to do.
