[Amps] Alpha 87a

[k7fm]

One simple way to improve the input swr to any amplifier is to add a 1 or 2 
db attenuator at the input.  The greater the attenuation, the greater the 
improvement in swr.  It does not make sense to do this if you barely have 
enough drive power, but the Alpha 87a drives easily.

A 1 db attenuator only needs a 15 watt continuous rating for most 
amplifiers.  Either a T or pi type will work.

A 3 db pad would mean that you would never have greater than a 2:1 swr into 
any amplifier, although the power dissipation would climb dramatically for 
the attenuator.

And, Happy New Year
