If you want to experiment with a HF helical coil antenna, then this short video from 9A4ZZ may prove interesting.
This antenna uses a large coil wrapped on PVC pipe. The closely wound coil is tapped for the various HF bands of choice. An inexpensive steel tape measure is used to form a simple elevated counterpoise.
The antenna seems to work well, considering the losses involved. You may be able to make this antenna using locally found parts and PVC pipe found at your local recycling center or neighborhood yard sale.
