Many thanks... makes it hard for me to be rotten all
the time when people are nice.

I have a 2 loop DB212-2 which is cut for 48 MHz. I want to use it for a 6M
repeater on 53.13. I've shortened the loops to about 53. Do I need to
shorten the length of the coax which runs from the antenna

First, don't expect to land exactly where you expect simply by adjusting the
lengths to a specific dimension. You really need to place the antenna on a
tower to adjust properly and use an antenna analyzer.

Reminds me of my first experience with a Cushcraft AFM-4DA
Dave,
I found some info on DB212 cable lengths doing a Google search.
A website by WA1ZYX has a couple of pages on modifying the DB212
for 6 meters and also cable lengths/matching and spacing of the
folded dipoles. No info on changing element spacing from tower
leg. This could affect the
Hi Ken,
I'd be interested in the web page url for the WA1ZYX web page
and the other information if you'd be willing to share it?
I have a DB-212 cut and working on 6m and the same type of
antenna on 2m with the director. I will as time allows
document those antennas and make that
If'n I remember correctly...
Fred Vobbe built his own 6m loop antennas for his repeater array -
maybe someone could arm-twist him for his story about the antennas and
harness.
(Sorry Fred - I know you'se busy...)

Yes please Jeff...
thanks
Yep I have 2 6 meter repeaters I would be interested in the data to build a
few DB-212 antennas

If you're building a Low-Band Loop Antenna from scratch...
forget the DB-212 and copy the Sinclair Version. The
Sinclair Low-Band loop has a lot wider band-width and it's
pretty much the same design... if properly done easier to
construct hardware wise.
