combustion engines. This imposes a requirement that the station site 

 be isolated from air routes and roads carrying heavy traffic. The 

 antennas are placed as far as possible from secondary roads which 

 cross their line of reception. 



The layout at Netcong is shown in Fig. 11. There are thirteen 

 antennas arranged in four groups with a receiver building for each 

 group. A headquarters building located at the road entrance contains 

 the wire terminating equipment, line repeaters, and voice frequency

testing apparatus. The power plant at each receiver and the entire 

 central terminal apparatus at the headquarters building are placed in 

 electrically shielded rooms to prevent radio noise disturbances emanat- 

 ing from them and reaching the receivers directly or via the antennas. 

 The radio stations described herein are pioneer commercial applica- 

 tions in the development of short wave telephone transmission. 

 Although progress has been rapid and far-reaching our knowledge of 

 the behavior of short waves is by no means complete. It is reasonable, 

 therefore, to expect that the future holds many improvements and that 

 the information obtained by further fundamental investigations may 

 materially alter both our views of the transmission phenomena and 

 our ideas of what the apparatus and stations should be.
