The antenna is coax-fed at the apex, with one leg running down adjacent to the tower. HOWEVER, the 40 meter band shuts off like a light switch here in upstate NY a couple of hours after sunset. The characteristics of such an antenna vary greatly from installation to installation, but generally a sloper presents a very high impedance on harmonics and they are usually single band antennas. A stealth end fed wire for 80 - 10 meters Kevin Loughin. , dipoles and slopers) did not work at such wide band. This is the price paid for multiband coverage and physical short- ening. A dipole is basically a length of conductor (wire) split into two portions and signal is taken off at the split. The end of the sloper wire has no mitigating factors, so the RF potential can be very high. I made antenna input impedance measurements at the following mounting heights for both my 160 meter and 80 meter half slopers. The "top wire" covers 160, 80 and 40 meters. with the sloper showing a consistent 5 dB improvement over the V.

SPECIAL NOTICE INSTALLATION &TUNING NOTES. This is a very simple antenna to build. I have also worked close to 500 digitals contacts also on 40/80 meters. It can be designed for use from 160 thru 10 meters very easily using the standard 1/2 wave dipole formula: 468/freqmhz = total length (ft) end to end The exact length is not critical! If you don't have room for the 160 or 80 meter versionthen design it for 40 meters and up!. Unlike trap antennas, there are no capacitors to break down under high RF voltages, and a tuner may be safely used for multi-band operation if desired. 22 Different Wire Antennas. The Par End-Fedz ® are a full length half wave dipoles, but with an important difference. The exact length depends on the characteristics of the area surrounding your antenna, including height above ground. The antenna's polarization is vertical. Directivity is away from the supporting metal mast or tower, toward the lower end of the sloper. MATERIALS: One 33-foot/10. I have a fan dipole for 160,75,40 meters it is fed with 80 or 85 feet of LMR-400 coax the transmitting is okay but the receiving is kind of noisy what can I do to make it better I will leave leave my email to you and I can tell you what I have on my coax feed to choke it I have it on the antenna feed line and when it goes in the ham radio office too they are snap on rings for coax that I. They are 102 ft. HOWEVER, the 40 meter band shuts off like a light switch here in upstate NY a couple of hours after sunset.
