JI1FGX/DU9 Business Antenna Construction(2010/12/17)
A customer recently asked us to install an antenna that he described as a mystery antenna.
The antenna looks like it has been used for a long time, and several repairs were made, such as a broken element and a disconnected joint of the coaxial cable.
Check with antenna analyzer after repair I was very interested in it, but 152MHz had the lowest SWR. Still, the bandwidth seems to be surprisingly wide, and there are places where you can get periodic tuning from 138 MHz.
Well, I guess that's about it.
Pipe extensions to replace stays on pole towers that had stopped in the middle of construction. Mr. Lotlot is rising in the blazing sun.
Five workers in all. The salary is 1,500 pesos ($3,000) for Lotlot. 1000 pesos (2000 yen) for other workers This was still a very well-paid job for them.
I also got 1,000 pesos from Gigi (come on, that's too cheap for Japanese). ."Because all you do is solder coax.Because..."
Installation of antenna on 21mH pipe tower Antenna installation costs 10,000 pesos (20,000 yen)
I got him to buy RG8 and solder the connectors, which is my job. Mr. Lotlot trying to connect that cable to the antenna
Charlei to install coaxial cable run
Used Alinco DR-135 for 13,500 pesos (27,000 yen) Stabilized power supply was not in stock, so I loaned him the one I was using. SWR was measured and it was generally 1.6 from 138MHz to 150MHz.
The two-day job brought in 23,500 pesos (47,000 yen). Even after deducting salary, 18,000 pesos (36,000 yen), it is still quite a good income.
Customers were very impressed with the Japanese manager who gave detailed instructions during construction.
