Thanks Tom, Pete and Chad,
from the diferent options maybe will be the Top Ten A/B for the moment.
A second SixPack is good but very expensive, and really we are starting in
Muti Single, so two radios listening in the same band as Chad suggest are
far away from our operation posibilities, hi hi.
A stackmatch is posible, I have one for a stack of 3 monobanders in 10 mts.
I think you need to have similar antennas to stack, since I have a Yagi and
a Delta Loop don´t know if will be good in my 40 and 20 mts situation (Yagi
and delta loops)
The A/B device seems is what I have in mind, I don´t find the manual, but
seems you can install it before the antenna side of the SixPack and remotely
swith from the desk in a way i don´t see in

I also have a Bandmaster from Array Solution that I not installed yet, but
hope the A/B from Top Ten will work when I have it installed.
The idea is to have in the operation position the SixPack control box, the
StackMatch for 10 mts control box, and another small boxes for the other
bands where I have more than one antenna, actually 20 and 40 mts. and NO
coaxials in the desk!.
I also have 2 beverages. I use a TS850SAT with the mod for RX antenna. And a
MFJ-1700C antenna selector that allows me to select manually any TX antenna
and any RX antenna (the main TX and the beverages). I have actually it
installed to select the RX antennas until i find a better solution for the
RX.
Thanks,!

Asunto: Re: [TowerTalk] 2 antennas selection
Tom VE3CX gives a good solution.
Another possibility is to use the Top Ten A/B switch (see
http://www.qth.com/topten/abss.htm) for each band you have two antennas, and
put this before (the antenna side) of the Sixpak.
I chose something similar to Tom's suggestion to use two sixpacks, but
instead, I homebrewed a ten-pack. I also have a "primary/secondary" toggle
switch with throws a small 4PDT relay. The common is the band decoder
output, the NC goes to my primary antenna select control signal to the
ten-pack, the NC contact goes to the secondary antenna's control signal to
the ten-pack. Whenever I'm on a band that has two antennas, regardless of
band, this single switch will take me from my main antenna to my secondary
antenna. I have another primary/secondary switch on my 2nd radio's as well.
Upon reflection, you could also send these control signals to the A/B
switches above and just use one sixpack.
The benefits of using two sixpacks (or similar) is that you can listen on
the other radio on the same band. The A/B method doesn't allow this.

Hello,
i have a new sixpack. It have to connect one antenna per band, 10 to 160.
I have 2 antennas per band for example in 40 and 20 mts. So I am looking for
a device that allows me to select one of this two same band antennas, just
with a small cable to the desk.
I can add a 2 positions Daiwa antenna selector, but I want to avoid the
coaxial in front of the operation position (I need the Daiwa in front of me
to change antennas)
So maybe is something to do that, just connect the antennas in the wall with
the sixpack and a wire with a switch to change antennas for this bands where
I have more than one antenna.
Thanks,
