[Elecraft] WG: Antenna question

[WILLIS COOKE]

I am all for caution!  That is why I suggested  to start with 100 mw and work up rather that full power and take your chances.  There is also a big difference in the selected antennas.  Either a Carolina Windom or a classic Windom has a lot of vertical polarization while a Yagi has very little.  Also my opinion of the quality of a K3 versus an FT-2K is very much higher, but I think the ability to turn the power down to sub QRP levels and the difference in antennas is very important.

Hi Willis,

I killed an FT-2000D with a windom on ANT1 and Groundplane on ANT2...they were both about 20feet apart!
Before that happened that on 15m my SWR of the windom was bad when the GP was connected..so the isolation of the FT-2000D was pretty poor.
But this was, after speaking to other FT-2k owners, only an issue with the 200W version.

Using now a 2 el Ultrabeam (by the way cool antenna for small spaces ), HF2V Vertical, Longwire and 3 Band Windom but haven't tried this with the K3.
Using a 4 x switch on the roof of the house now and one cable going to the shack.

So I am pretty cautious with 2 ant on one rig...hi

Since the K3 will do the QRP thing down to 100 mw, think about installing 
the vertical above the beam on the mast and gradually try more and more 
power out of the K3 until you start getting some overloading.  At least you 
can find your answer without frying anything and some folks find QRP lots of 
fun.  Maybe you will too!

This might be a stupid question, but here goes.

I have a small lot.  I currently am using a 3 element Yagi that barely fits 
on the property.  I was thinking about getting a vertical as a second HF 
antenna.  If I put it up it is going to have to be pretty close to the Yagi.

I have a dual receive K3.  If I have both receivers going, one on each 
channel, and I broadcast on one of these antennas, am I in any danger of 
overloading and frying the other receiver?
