18,24MHz Fan Top Antenna Height Construction (2025/02/17) 
18,24MHz Fan-out Dipole Antenna
The 18MHz element is a pulley attached to the roof of a garage, about 5m high.
The 24MHz element is only about 4m high.
As expected, the flight performance of the 24MH was poor, so I decided to set up a pole.
I bought a 1 1/4 inch metal pipe from Clarin Hardware for 1,131 pesos (approximately 3,000 yen).
I also bought a 35m rope for 210 pesos (about 550 yen).
I took it to a nearby tricycle factory and had them weld the rebar to hang the pulley.
The cost of rebar and welding work was 100 pesos (about 265 yen).
I was able to purchase the hardware and request welding by myself.
When my pronunciation is poor and people can't understand me, I always have to rely on Google Translate...
I tied it to the bed of a Mitsubishi Strada with a rope and carried it.
The length of the pipe is 6m
Welding work
I had a 6m pipe attached to a 3m pole. The pipe is 9m high.
The cost of welding the pipes is 400 pesos (approximately 1,060 yen).
Total 500 pesos (1,325 yen)
The 24MHz element, which was at roof height, is now 9m above ground level.
Up until now, when I called out CQ on 24MHz, it was a miss, and when I called, there was almost no response.
Since we increased the height above ground to 9m, we have been getting quite a few calls.
(Maybe the conditions were just good today?)
I wish I could make it higher, but I'll have to put up with this for now.
Next, I would like to consider installing a 28MHz antenna and a 3.5MHz antenna.
