ETS-Lindgren's Model 3110C Biconical Antennas combine several unique features to achieve high levels of performance. The balun, feedline, and element cage design give the model 3110C response curves that are almost linear, making it ideal for swept measurements. The antenna's insensitivity to orientation in the vertical plane helps eliminate any unnoticed or unrecorded change in orientation as the cause for a change in test results.

To achieve this kind of performance, the balun is designed using an unbalanced-to-balanced transformer. This results in very even current transformation. Ferrites are also placed along the feedlines, reducing common mode current that can interfere with the antenna pattern in the vertically polarized measurements.

The 3110C is also easy to mount, and now features a stinger mount with square collar. This collar allows for easy polarization alignment when using an ETS-Lindgren mast.

Common applications for the model 3110C include measurements to MIL-STD specifications, ANSI C63.4, FCC-18 and EN 55022 emissions testing.

Unique Element Design

Some biconical antennas exhibit an electrical bump at 281 MHz, but ETS-Lindgren's biconical element crosspiece design improves performance by eliminating this problem. The biconical's crosspiece connects the center element to the outer element diminishing the bump. Another enhancement is element cages that cannot be overtightened when screwed into the balun.

Improved Balun Design

With a balun constructed from a micro-transformer, the 3110C has a excellent impedance match and balance between 50 and 200 (the impedance of the biconical elements), for the whole frequency range of the antenna.

Compact Size

Because of their compact size, ETS-Lindgren Biconical Antennas are ideal for anechoic chambers and shielded enclosures.

Quality Construction

Biconical elements are constructed of lightweight corrosion resistant aluminum, providing years of trouble-free indoor and outdoor service.
