You can spend about $25 to turn the Jackite 31′ pole into an all-band HF Antenna that will give you all bands between 80 and 10 meters, without a tuner. There are mods for 160m and it might even work on 6m with some tuning.

The Jackite pole on the other hand is very robust, but also a lot more expensive. It also requires a sturdy mount, as it is much heavier and has a higher wind load. So the winner really depends on your ...If you are only interested in the LF bands, an inverted L (approx 40ft high and 132ft long) is a good simple to construct antenna which produces very good results, especially if you don t have a lot of space for radials or elevated counterpoise wires.
