Satellite antenna installation (2026/01/10)
The satellite communications radio is an ICOM IC-820H and two Kenpro rotors, the Az (KR-400) and El (KR-500).
The controller that controls it is Fox Delta's ST2-USB
The coaxial cables are LMR400 (equivalent to 7D-FB) for UHF and 5D-FB for VHF.
However, the LMR400 has an N-Type conversion connector for the SMA connector.

When I tried to connect the UHF coaxial cable LMR400 to the radio, the base of the SMA-N type conversion connector broke.
Truly Chinese quality.
The thick cable has an SMA connector, so I wasn't sure it could withstand bending force, so I ordered a conversion cable online from Shopee.
The satellite launch is about 10 days away.
The antenna installation was scheduled for Sunday, January 11th,
but was suddenly started by a family member on the evening of January 9th.
The two rotators and the glass fiber pipes were quite heavy, but we managed to pull them up with ropes and set them up.
The compass is aligned to the north.
 
This work was done by two people, Ronel and Rosmar.
I paid them 500 pesos (USD 8.5) each for their work.
By the time I installed the VHF cross yagi, it was already sunset.
When I checked it this morning, I noticed that the U-bolt on the VHF cross Yagi antenna had not been tightened properly, so the antenna was pointing downwards.
I asked Lobmar to come over on Sunday to fix it.
 I pushed the antenna from below with a pipe and it easily changed direction.
It turns out the U-bolt wasn't tightened properly.
