Re: Antenna question

Paul Smith
 


   Nearly 20 years ago when we were living on our farm I had a loop made with 12 THHN stranded wire. Insulators were egg shaped porcelain. I suspended the loop on the corners and one other place because there was a good tree there. I used more of the THHN wire and window weights for tension. I ran 450 ohm to my home brew tuner and no balen was used. When it stormed I unhooked the feed wire shoved it out the wire tube I had installed in the wall and tied the ends of the feed line together.
My farm was on nearly the highest ground in Allen County so if there was lightning we got it.
I saw the loop more than once sparkling with static. It sure was a good antenna though. It came down in another wind storm and I never put it back up.
Have fun!

I would like to get some input on building an 80 meter sky loop antenna that I will use on 80 and other bands with an antenna tuner. I have some nice tall pine trees to run the corners to and I plan on joining the loop to the house with 450 ohm ladder line. Just under the edge of the house I will install a balun and bring it into the house with low loss coax. Please make any comments or offer any advice you can. I am hoping to learn from your experiences. Some questions I have are:

- What kind of wire should I use for the loop antenna

- What type of rope that will hold up to the UV and time (so much just falls apart these days)

- What balun, 4:1, 1:1 ?

- Is 450 ohm feed ladder line the best to use? This part will be about 80 feet long.

- Has anyone ever had any issues using delrin for the insulators?

- I am thinking about placing a screen door spring on each corner to allow the trees to sway in the wind… anyone ever tried that. Or should I just counter weight to opposing corners of the loop?

- How’s the best way to protect this setup from lightning?

Hi Group!

Saw a reference to this on another e-list and I thought that it might be
of interest to some of the people on this list...

It can be used on your computer, or on a Raspberry PI computer, so you could
make it a portable RX or remote the RX and send the data over a network
from the remote site. Looks like a cool device!

Re: MFJ Cub transceiver

Good evening Doc,
I have the 20m version and I like it. I inherited it from a Ham chum of mine in the UK when I emigrated here to the USA almost 13 years ago. The mod I made was to fit a BNC antenna receptacle in the hole intended for it just above the RCA antenna receptacle, I've never been a fan of RCA fittings for RF connections.
For the money I thinks it's a grand little wireless and it has been /P with me a few times over the years.
Enjoy, I would go for either the 20m or 40m models. Others may have experience/opinions on the 40m version.
Vy 72/3 es God Bless and HNY. Peace my friend.

Also, what band/frequencies do you recommend for QRP CW activity.  I am definitely QRS and need advice on the best band/freqs.

Hope you have a safe and happy New Year.

I got 1 !!

Dale Putnam
 

Yes Sir!! Sure did.. got 1... just 1.. a lonely 1..
and with 1.. it is tuff to make 2... but at sunrise... it is a sure thing..
somehow.. that lonely 1.. will eventually become 2...  degrees.

with 8 inches of fluffy, dry, just waiting for a wisshp of a breeze to travel...
that lonely 1.. and the white stuff.. is fixin to make it a bit more interesting to get out and
chase after all those... "just gotta have its... can't miss this.... look over heres... ".. as if there
is desire to go run through the crowds, and grab anything with a sale tag on it.  "Save here"...
hmm...

The Stew is on .. you know.. the Stew Perry test?..

http://www.kkn.net/stew/
and I am going to work it.. but first.. a bit of coffee.. then I'm going to tune a bit higher in the band..
about 1.835 - 50... see if I can stay away from the broadcast interference.. until after dark thirty...
Good Luck teasing the Prop Princess.

Have a great day... es night....   even with just 1F

Have a great day,
