Thanks for the insight. Ill do some additional experimentation.

Yesterday I spent several hours testing dipoles, longwires, a raised up-and-down fling wire, and an off center fed dipole. The area I was working in was not optimal; low swampy ground and shooting straight into power lines. However, mission dictates location. Needless to say I had no luck hitting the base station.

Today, I was able to move locations. I had an open area in the jungle and a 30ish foot tree to work with. I used a sloping V antenna. No grounds, no resistors, and a coax transmission line off a balun from a SORAK. First shot out of the box I hit the base station and data was sent in a couple minutes.

If I have time tomorrow, I will go to the same location and test out the previous antennas and see how they compare in the new location.

I do have one question. What is the difference between radio waves propagated over land and over water? Say if you shoot over an ocean, will the waves propagate more efficiently?

Thanks for the insight. Ill use this to build up my HF comms bag.
