TELEVISION TRANSMISSION OVER WIRE LINES 81 



Conclusion 



The experiments so far made in the transmission of present-day tele- 

 vision indicate that wire lines can be provided at least for moderate size 

 intercity networks; also, that such lines if properly equalized for delay and 

 attenuation do not materially alter or distort the transmission of present- 

 day 441-line images, even though the frequency band is somewhat narrower 

 than the nominal 4-mc band. 



The use of ordinary telephone cables for local television connections 

 also has been found to be feasible for all of the conditions so far tested. 

 The 2f mc television transmission experiments over wire lines reported 

 herein have proved very successful. Experiments with wider band coaxial 

 systems are being undertaken.
