Eavesdropper Sloper

The Antenna Supermarket company, famous for their Eavesdropper™ trapped dipole, also offers the Eavesdropper Sloper antenna that covers all the major shortwave broadcast bands plus medium wave and requires only one high support. Includes PL-259 type fitting for user supplied lead-in and is 67.5 foot (21 meters) long. The Sloper is electrically loaded by two coils, providing a substantial physical shortening of the overall length of the antenna. Each of these coils has a resonant frequency, and they act like traps to isolate portions of antenna on their resonant frequencies thus allowing multiple resonance on the antenna. In addition, the short parallel section of ladder line at the beginning of the antenna element provides yet another resonance. Both coils are enclosed in an ultrasonically-welded, hermetically-sealed, ultraviolet light-protected coil cover assembly. This protects the the coils and the factory solder connections from the weather. The Eavesdropper antennas now include a ZapTrapper™ static arrestor. This separate device has a PL-259 plug at one end and an SO-239 jack on the other end. (The Sloper does NOT include: coax lead-in, ground wire, ground rod or house shown in illustration). The impedance to the receiver is 50-70 ohms unbalanced. This antenna is largely omni-directional, but will slightly favor reception in the direction of the downward slope. The Eavesdropper covers these major bands:

Medium Wave (  0.54-  1.70 MHz.)
120 Meters (  2.30-  2.50 MHz.)
  90 Meters (  3.20-  3.50 MHz.)   75 Meters (  3.80-  4.00 MHz.)   60 Meters (  4.75-  5.06 MHz.)
  49 Meters (  5.95-  6.20 MHz.)   41 Meters (  7.10-  7.30 MHz.)   31 Meters (  9.50-  9.78 MHz.)
  25 Meters (11.70-11.98 MHz.)   21 Meters (13.60-13.80 MHz.)   19 Meters (15.10-15.45 MHz.)
  16 Meters (17.60-17.90 MHz.)   13 Meters (21.45-21.75 MHz.)   11 Meters (25.60-26.10 MHz.)

The user must provide their own coax lead-in. If using a communications receiver, the coax lead in would have a PL259 connector at each end. Common pre-made lengths are listed in the table below. All the Eavesdropper antennas are for receive-only and are covered by a one year limited factory warranty. Made in the U.S.A.
