Tim: How much SNR should the link be from MVHS to new BARC clubhouse?
Chuck: 20 dB minimum.
Tyler: To renew membership at DARA and obtain 'fob' access to clubhouse
in order to upgrade and maintain the AREDN services therein.

I did some estimates comparing the similar path from MVHS at 120' elevation clear of any trees for miles:

• to N8NQH: 2.6 miles, Tim is at ~70 feet elevation(?) and surrounded by trees.
• to BbHS: 2.5 miles, assuming 25' elevation, clear of trees for 0.3 miles toward MVHS.

NC8Q-MVHS-Bellbrook: using 25 dBm TX, 24.5 dBi antenna and achieving ~25dB SNR.

N8NQH-to-MVHS: using 28 dBm TX, 16 dBi antenna and achieving ~25dB SNR.

Else, these 2 paths are somewhat similar.

BbHS:
The tower appears to be 72' tall.
Near the top of the tower:

• There is a unpopulated off-set vertical mast.
• There is a broken 2.4 SISO dish antenna.
• There seems to be an in-service UHF omni-vertical.
• There seems to be a SHF dish aimed about 330 degrees azimuth.

 
The UHF radio coax seems to enter the building adjacent to the tower.
So do the AT&T telephone cables.
Likely only DSL internet will be available. :-(
