I have some doubts about installing and inverted L with elevated radials for 160m. I have been searching in Google and find some contradictory information, so I would appreciate very much if you can help me with your own experience.
The antenna would be supported by a 16 m (52.5 ft) high fiberglass pole placed on top of a 3m (10 ft) high small tower with the horizontal part of the L slopping down to a 5 m (16 ft) high mast about 23 m (75 ft) away. Two to four tuned elevated radials can be placed, although they will have to be bent due to space restrictions. Now the doubts: What impedance can I expect at the feed point with this configuration? How to match it in order to feed it with a 50 ohm cable? Some pages say that no match is required, only a choke. Other pages say a hairpin is necessary as the impedance can be too low. So other say that a tuner at the base is required? I am confused L What performance for DX can be achieved by this antenna? Is it really good or do you have some better suggestion for a really small lot where no ground radials are possible? Would it be worth to use a higher fiberglass pole, let's say 4 m (13 ft) higher, in order to lengthen the vertical section of the L? Would the difference be noticeable? Anyone has real experience setting up this antenna with elevated radials? Most information I can find on Internet is related to ground mounted antennas. Thanks in advance! 73.
