Antenna for 18 MHz. After the temporary assembly, we are having them climb the coconut tree and measuring the SWR with the antenna analyzer.
Trial and error with MMANA Direct connection of coaxial cables is possible. I have emailed JQ2GYU many times for help with the design!
This would be a good antenna to start with.
Purchased another aluminum pipe at the aluminum sash shop that I located when building the 50 MHz antenna on July 10.
The joint is split and secured with a hose band. At this point, the conductive compound has not yet arrived, so it is a temporary fix.
This is the power feed section Divided into two parts in PVC pipe A square piece of aluminum is cut and fixed to the boom for strength
Here is the normal element
The skeleton of the finished antenna is being transported to a vacant lot behind the house. It is heavy enough for one person to carry, weighing 5 kg in total.
We're working before the morning sun gets too strong. It is too hot to work under the hot sun during the day.
Connection of each element
Lotlot climbed a coconut tree with an antenna!
Good SWR After this, I took the antenna down several times and fine-tuned it to drive the SWR down.
These are the three sacred tools for creating antennas for our home MMANA installed on a computer, a book purchased through Amazon mail order on the Internet, and MFJ-259B The laptop in the back is a dedicated DX cluster computer
