Hi. I have a transmitter for 160m band about 200-300w r.f output power. Now i am using an (5/16)X(wave length) inverted L. I am looking for an antenna which will provide strong local signal. I have r

There is very little difference in the pattern of a 5/16 inverted L and 1/4 inverted L that has the bend to horizontal at the same height, assuming a bend even roughly half way. The lower the bend th

hi. thank you for your answer. What elevation angle has the 5/16 inverted L and what elevation angle has the 1/4? Must i will reduce the total lenght from 5/16 to 1/4 for higher local signal or the d

The actual difference will vary somewhat depending on where the bend is. The simple one I tried had only one degree difference, 25 and 26 degrees, but the difference between the two elevations was on

The difference in the vertical radiation angles between the 5/16 and Inv L is small because with both antennas most of the radiation comes from the vertical section. Radiationwise, these two atennas

your answer. What elevation angle has the 5/16 inverted lenght difference is just a 5/16 inverted L? If i keep the 5/16 inverted L what i change to increase the signal? Now i am using 6 radials (4 1/

hi again. I have a more question. As you can see at this draw http://tzitzikas.webs.com/transmitter_installation.JPG the feedpoint of my antenna is founded in the transmitter's metal house!!! I have

Aside from miscellaneous capacitance, which won't amount to much on 160, just changing the feed a little, I don't see any real effect. You should connect the metal house to the radials and to your gr
