Can an antenna work while laying on the ground?

Image
The short answer is "yes."  A lot depends on the conductivity of the soil, actual height above ground, and othe environmental factors. In this video, Kevin Loughin (KB9RLW) experiments with "ground-hugging" HF antennas and comes to some interesting conclusions. While on-the-ground antennas are hit or miss for transmitting, they do remarkably well on receiving. If this topic interests you, please use your search engine to find articles from Mike Toia (K3MT), whose "grasswire antenna" will give you some interesting ideas for operating in noisy and deed-restricted housing.

Near Vertical Incidence Skywave Propagation

Image
If you need reliable region-wide HF communications, please consider a Near Vertical Incidence Skywave Antenna. In this video from Michael Martens (KB9VBR), we get an excellent introduction to NVIS and the antennas that can fulfill this role. NVIS HF antennas are perfect for regional and statewide emergency communications, providing strong signals up to almost 300 miles (480 km). If you can't see the video, please insert this title URL into your browser:  https://www.youtube.com/watch?v=fvZ7z-6wAy0 Here are some comments from Michael (KB9VBR).   Near Vertical Incidence Skywave Propagation is an effective form of HF communication for stations in a 100 - 300 mile range. Ideal for Emcomm, the emergency communicator should be familiar with the use of NVIS antennas and propagation.

The Double Bazooka Antenna-A Review

Image
Thanks to Rob Wagner (VK3BVW) for this excellent review of the double bazooka antenna. If you have the space to erect this unique antenna, you will be rewarded with an excellent signal for the 80 and 40 meter ham bands. If you can't see the video, please go here: https://www.youtube.com/watch?v=9xfpcD6xuSo Here are some comments from Rob (VK3BVW): Here is a review of the 40 and 80 meter band Double Bazooka antennas as used on the HF shortwave bands. This will be of interest to amateur (ham) radio operators and shortwave listeners. This particular antenna comes from IAC antennas (www.iacantennas.com) where more information can be obtained.
