help needed regarding Txline antenna
(OP)
Hello All,
I am collecting info about transimission line antennas,I have a doubt for any transmission line antenna do we need to terminate the line with its characteristic impedance? or is there anything else? I dont know its not making sense to me. Can anybody explain it to me or any link where I can find some info.
thanks in advance

RE: help needed regarding Txline antenna
If you don't terminate the leaky line, then the emission performance at the far end might become a function of position (due to standing waves caused by the open circuit at the far end).
On the other hand, if most of the energy has been leaked-out already, then there wouldn't be much RF energy at the far end anyway.
Check with the OEM for recommendations (application notes).
It would seem likely that smooth performance would require a matched load at the far end, and that there would still be a fair amount of power even at the far end.

Thanks for the reply.
May be its dumb question but I dont understand what is OEM you mentioned about checking application notes.
thanks

Can you send me the link if you find what VE1BLL is talking about.
thanks
RE: help needed regarding Txline antenna
Appreciate your help. Like antenna21 mentioned I dint understand which application notes you are talking about?
once again thats for the help.

OEM = Original Equipment Manufacturer
For something like leaky coaxial cable (a technology that not everyone is familiar with), I can only assume that the OEM website would (or should) have a section called Application Notes (or similar).
If not, then phone them up.
If you don't have a specific product in mind, then research such products on the market.
