[Elecraft] Balun Questions

[Jim Allen]

Ok, so this morning, I went out to the shack and whipped up a balun, from a G3TXQ design I found on the website of W5DXP.com.  It is coax wrapped around a ferrite core, with appropriate connectors in a plastic weathertight box.  I used RG8X coax, a 2.4" core, not sure exactly what mix, and 11 turns.

How do I test this device to get its properties, impedance at various frequencies, etc?  

It appears to function when I put it inline.  The KAT100 seems happy.  It produces a decent match on 40-10m using the 44' long rotating dipole at ~37' fed with 450 ohm twin lead.  I have no idea how efficient it might be, of course, if at all.

I still don't hear the VP8 much above the noise. :>(
