[Tech-Assist] Marti STL funny readingsHere's a head scratcher.

[Ronald J. Dot'o Sr.]

Hi gang,

I just installed a Marti STL-20 TX on 944.375 (freq not relevant to 
situation).

It drives a Scala Paraflector antenna thru about 80' of 1/2" Heliax with 2 
1/2' RG-8 pigtails on each end.

The TX is putting out 24W into a 50 ohm dummy load with 0 W reflected.

At the antenna end I'm getting 16 W into the same dummy load with the 
losses.

Now here's the strange thing:

Into the antenna instead of 20 W out of the TX I'm getting about 35 W 
indicated with about 1.5 W reflected.

I checked this with my Bird 43 with a 400 -1000 Mc. 25 W slug which pegs the 
meter and my Telewave 44 thruline which doesn't require slugs and has a 50 W 
scale.

Both thrulines show 24 W into a 50 ohm dummy load and almost double that 
into the antenna.  I'm sure that the STL-20 isn't magically almost doubling 
the TPO into the antenna.  Both thrulines show about 1 to 1.5 W reflected.

What's going on here?
