At our contest station ED1R we have no space for permanent Lowband Verticals. Each Contest, the verticals have to be installed temporarily in a field nearly. Especially the deployment and removal of the antenna radials is very time consuming. Over time we optimized our system which reduced the required time from 2 hours down to 30 minutes.
Fastron is key
Screws & nuts are a bad choose when things have to be done fast. Changing to Fastron terminals improved significantly the speed of deployment. We mounted on the ends of each radial a male and female terminal.
We also added to male Fastron Terminals on each position of the radials plates.
The female connector of the radials are plugged to the male connectors on the plate. No screwdriver is needed. Just rapid Plug & Play.
When we started using Vertical antennas on 160m and 80m, especially the removal and storage of the radials was extremely time intensive. We had to roll up each radial individually, fix it with a piece of tape or a tie-wrap. The picture below gives you an idea how much work it was.
They are available in all DIY stores for less than 20€ a piece. At ED1R we applied this to the radials. Look how they are stored now:
Now you might get an idea why we crimp beside the female Fastron connector, also a male connecter. Whenever the radials are removed from the plate, they are connected in chain to the form one single long wire on the cart.
Deployment & Removal
Radials are now very easy to deploy. In practice we found that radials are fastest deployed with a team of 3-4 persons. While on person stays at the cart and connects the ends of the radials to the plate, the other 2-3 deploy the radials in the field, directly from the cart.
Radial removal is best done by two persons. One disconnecting the radials from the plate and connecting them into a consecutive chain on the cart, while the other person turns the winch of the radial cart.
The time needed for deployment and removal of radials (approx 40 – 60 radials per Vertical) could be reduced from 2 hours to less than 30 minutes with this technique. It takes some initial time to crimp the fastron terminals on the cables, but once the solution is in place, signifiant time is saved whenever the radials have to be deployed.
