The inverted l antenna is a common antenna for the 160 meter and 80 meter amateur bands where typical wave verticals are impractically tall for most amateurs.
Inverted l antenna for 80 meters.
83 tri band beam for 20m 15m 10m.
Shortened inverted l antennas are 65 of the overall length of the full length inverted l providing the same high performance in a reduced size.
The center fed inverted l has the potential to be a quite satisfactory all band wire antenna suited to certain environments.
For a compromised antenna system it performed as well as my 80 meter inverted vee.
160 meters and 80 meters.
This wire is an inverted l with about 25feet hanging vertical and the rest horizontal.
Below about 90 overall wire length the antenna becomes essentially a 40 meter and up inverted l.
82 300ohm ribbon dual band dipole.
Antenna construction centers around a loaded wide spaced high q coil that feeds into 50 ohm coax in combination with 300 ohm transmission line end sections.
80 inverted delta loop antenna for 160m.
So if i assume the popular dipole formula 468 f mhz is correct then on 80 meters and applied also to a quarterwave then i would see resonance at f mhz 468 66 2 3545mhz.
An inverted l antenna is basically a wire antenna typically to wavelength long on the band it is designed for.
In the fall of 2007 i was able to install my first amateur radio tower while this certainly was a huge improvement over my humble butternut multiband vertical my new tower had a major shortcoming a lack of antennas for the low bands.
Shorter antennas down to about 90 overall wire length can be built and used on 80 meters.
Planning a dual band inverted l for 160 80 meters modeling a quarter wave inverted l antenna for the low bands.
If you can find a tree house pole anything elevated which can be used to support the end that will work better than when sloping to the ground.
81 inverted l for 160m.
86 fan dipole antenna for 80m to 6m.
85 half rhombic directive antenna for 20m to 6m.
The wire is exactly 66ft long.
Shown here is an inverted l with its long leg sloping to the ground.
Although the radial system is far from ideal the inverted l has been able to gather both local and dx contacts on 80 40 20 15 and 10 meters.
How to build an inverted l for the low bands 40m 80m and 160m an inverted l is just like a vertical apart from the fact that instead of going straight up like a tuned quarter wave it turns 90 degrees somewhere.
84 mini horse yagi antenna.
The inverted l antenna and nvis.
