[aprssig] Re: PHG Protocol Antenna Gain

[Robert Bruninga]

Ev makes a good case fo PHG to be in dBi and not dBd.
I'm thinking of changing  it to dBi.  It was not really defined 
in the spec.  I nailed it down to dBd a few months ago,
but think that dBi is better.  Bob, WB4APR

Hi Bob,
I hear word that you were recently asked about the Gain-scale for PHG
and 
decided it would be dBd.  Of course, it is your protocol, but may I ask
that 
you consider dBi?

The argument for dBi goes like this...

...since there is no negative gain component in the PHGra/ protocol
and
...PropNET uses PHGra/ in every transmission and
...on HF, there are folks with antenna "gains" that are less than a
    dipole; such as those running "Hamsticks" on 10 meters, etc

Therefore, PropNET has already adopted a dBi scale for PHG.

Would you consider similarly adopting dBi-based Gain as it applies to
PHG as it 
is used within the APRS service?

Kind regards,
