Biqua Sales

Hey guys,

Just wanted you all to know that I've put together a quick web site
to sell Biquad antennas.
Only reason is some of you may not know how to solder and things like
that so I do that for you and make
a few bucks just to keep the site up! Really not making much per
antenna but I like building these things.
I've got some really cool ideas in mind so check on the site often!
Check it out! http://www.biquadantenna.com

Thanks Guys

Pete

Jeff,

The antennas work great! You can't believe how much the signal
increases right after hooking this thing up!
Right way, wrong way the Biquad antenna, and the way I build them work
great!

DTC,
You're exactly right! It is naked and I plan on selling one in a
case also!
Thank you for the good idea!

Jeff,
I'm not asking you to believe me. Believe what you want.
Yes there are (other) antennas out here for cheaper but certainly NOT
as directional
as this Biquad.
You and I emailed each other about a year ago, you said you would
help me in soldering up some
connections for a USB adapter. Every time I emailed you, you always
had some excuse and was
always complaining about something!
Funny we meet up again!
Please don't be so critical with me. You know this antenna works good
so why bash me?
I'm just having fun and trying to share a good product.

Thank You
Pete

Jeff,

You wrote:
Groan... I don't like the way you did not extend the coax cable all
the way through the reflector and up to the antenna. The
configuration you're using will work, but it's far from optimum.


I am not using coax but only the N female panel mount connector.
I'm confused on how you mean or how to make it better!
Sorry for all the problems but I would like your help.

What happened? Loose power?
Are you anywhere near Hurricane Fay coming in?
I'm in FLorida so we're kind of watching it.

I've seen most of those sites but two I haven't. I understnad about
the feed now though!
Have to get that baby shielded and away from the feed wire huh?

I'll work on some things, let you know how it goes!

Thank you sir!!
Pete

arrgghh can't hardly read those Validation words to send these. LOL
