[Lowfer] antenna locations - too close?

[Eric Smith]

I've just activated a medfer (UWL) at 1700 kHz ... moving to 1702 as soon 
as my new oscillators arrive.

As you know the lowfer is next -- antenna under construction.

Click on the MF link to see the pictures.

I was thinking of mounting my lowfer antenna on the corner of the 
same building the medfer antenna is mounted on (as seen in pics at link, 
above).  They would be about 4 or 5 feet apart.  Any problem with them 
being that close to each other?

Thanks for all your help,
Eric
