I originally intended to set up my radarbox permanently in Hanoi...but due to various factors (the need for a monster mast, highrise buildings nearby, building regulations, radio interference, the incredible cost of shipping a proper antenna to Vietnam and the hassle of dealing with customs etc) I put the project on ice.
Now I just opened an office in Saigon (or Ho Chi Minh City for those who still like the idea of naming cities after people), perfectly located 3nm from VVTS.
The standard glideslope for rw 07L passes right next to my office window - at around 1000ft altitude on approach the aircraft are 0.4 nm away from my antenna, meaning that even with the standard antenna inside my window sill I already now get good returns from that direction :)
I've just signed a long-term lease for the office here, and in due course I'll set up a proper antenna mast on the rooftop which should clear most obstructions and give near 360 deg coverage, and invest in a slightly higher-gain, probably sealed (fiberglass) "permanent outdoor" type antenna.
I'm running airnav on my laptop for now (and need to take it with me sometimes), but as soon as I get a permanent antenna/mast, I'll use a dedicated box so that it will be online 24/7.
