Since I have a back ground in metal work, soldering etc I chose the torch. Learn something new every day. This creates a nice support for the feed line and also takes stress off of the solder joints. You have to stop, get out, and manually change the tap. Km4htd Dale in Kentucky. Excellent performance from one end of each band to the other end is obtained without retuning the beam. All this stuff was a lot to take in at the beginning.

End Fed 6 40 Meter HF Ham Antenna
Removing the single bolt from the top bracket allows the element to be rotated down to the ground. I guess you could call my "antenna" a field day special and nothing to be proud of! But, 80m is a big wide band. I push the coax up through this. Do NOT place too much focus on the exact lengths shown in the drawing. In the original article published in 73 magazine, it is nothing more than a simple folded dipole made from ohm TV type twin lead cut to the length of 63 feet 2 inches plus or minus 1 inch and is fed in the center with RG58 coax or some other 50 ohm coaxial cable.

And, by the way, what did I buy those parts and rope and wire and fiberglass and aluminum for in the first place? Not specified filter applied. The performance of this antenna depends entirely on the reflectors! That's how I learned how to make it work, and the comments of many on the Towertalk reflector. Or even sometimes beyond their interest level or desire for learning. I confess I am a procrastinator.
International amateur radio frequency allocations. Plastic 6 inch long tent pegs are one method used to secure the ends of the radials. The antenna is designed to be fed with 50 or 75 Ohm Coax Cable of most any length with a Balun. Don't be fooled by these "lossy" trap theories. It's probably not a great idea to use a hunting arrow, as there is likelihood someone on the other side of the aforementioned tree might be on the receiving end. This will help mitigate mismatches and stray RF due to using the antenna at frequencies other than what the antenna was specifically designed for. The heights you are suggesting would indicate the antenna elevation pattern will be very high.
