Installing your Hustler Vertical antenna.
All quarter wave vertical antennas need an earth system to work against. Imagine it as being the other half of a dipole. The popular way to mount a vertical antenna is at ground level. This is because a vertical antenna is often the best choice for a small garden.
It is a popular myth that radials have to be a quarter wave long. In fact they can be any length. The more wire that you lay down the better. Again, the common method of installing radials is to slit a hole in the ground and bury them. The wire can be insulated or bare.
If you really do have problems in even installing radials, then a couple of earth rods will work, albeit at reduced efficiency. And another tip os to make up a coax choke at the point at which the coax connects to the antenna. This can be easily done by winding around 10 - 15 turns of coax on a 4" former, fastening with plastic wraps or tape and then removing the former so that the coil is air wound.
