Lecher lines moved fronm my talk page     Lecher lines   Do you have any thoughts on the subject of tuned circuits for UHFSHF I am planning on expanding the page a little to make it more useful  Yes But I have to gather my thoughts The trouble is that you have reverted some of my corrections to this page in your addition Can you pleae be more careful when adding material that you dont destroy peoples improvements BTW can you please sign your posts by typing four tildes so we know who to reply to Thanks   I think that a clear need exists for the division between balanced and unbalanced transmission lines Many aerials are balanced such as the centre fed half wave dipole these aerials can be fed using a balanced line which is connected directly to the some old equipment or via a balun in the shack The other option is to use a balun near the feed point of the aerial and an unbalanced feeder This arrangement normally leads to higher losses but it is more EMC friendly While the use of long runs of balanced feeder is something which many people outside of the radio community are unaware of it is a concept which is very important and WP will be better if such things are included  Sorry I overwrote any improvements which another editor made but I was reverting some changes which had made the lecher line section into dire state where it was not in the correct order   Yes but we dont want to turn it into page on Ham radio solely its about transmission lines Sounds like we need a page on aerial matching however aerial feeders bal and unbal are I think are appropriate on this page
