End Fed Antenna For Short Attic

The radiator is 45 feet of genuine 14 black polyethylene coated flex weave wire.

End fed antenna for short attic.

One advantage of the end fed half wave antenna over an end fed random wire antenna is that it can be used on bands harmonically related to the band it is cut for without a tuner. Need lots of room keep. Once all the yagis were bolted in place on the mast i used my antenna analyzer to adjust their driven elements to provide the best match in the weak signal portions of each band. Attic antennas many types of antenna can be mounted in the attic if you don t have radiant barrier tech shield.

You would eliminate a source of unwanted interference. The wire itself consists of 168 strands of 36 gauge woven copper. So one cut for 40 meters for example can be used on 20 15 and 10 meters without a tuner to use it on 30 12 and 24 meters does require a tuner. Another stopgap measure would be to replace the coax with a length of insulated copper wire connected to the hi z terminal on the back panel of the frg 8800.

The floating coax shield but you will introduce another potential source of. Remote rf switch control box in the shack chooses which antenna is operational in the attic. If you do not have enough room for a 138 foot end fed sloper try a 67 foot sloper. Red is a 6 5m vertical fed against a large metal roof using a 4 1 unun 200ft of coax and an auto tuner at the transceiver green is the 15m long wire bicone antenna mounted in the loft yellow is a 40m long doublet fed with 450 ohm ladder line and an auto atu at the base.

I have found that an end fed outdoor shortwave antenna 138 feet long 42 05 meters will give very good results over much of the shortwave frequency spectrum. The par electronics ef swl is an end fed short wave antenna optimally designed for 1 30 mhz reception.
