ERI will highlight the thermal expansion-compensating MacXLine rigid line with bellows, as well as its Rototiller series of FM antennas.

ERI says the solution to eliminating sliding-contact wear is to eliminate the sliding. Expansion of the MacXLine inner connector is taken up with a flexible bellows, once put into service. Burnout and bullet replacement are eliminated, according to the company.

MacXLine is manufactured from high-conductivity copper tubing, outer conductors and PTFE dielectric disk insulators for mechanical alignment. Each section comes with a bullet/bellows assembly, stainless steel flange hardware and pressure-sealing gasket. Sizes range from 1-1/8 inch, 50 ohm to 8-3/16 inch, 75 ohm.

ERI says its Rototiller FM antennas offer an internally fed, fully pressurized system with welded feed connections, rugged brass material and TIG welding. The antenna’s configuration and the large diameter of the radiating elements contribute to its bandwidth capabilities, inhibit corona discharge and have a high immunity to weather-induced VSWR.
