Antenna question

kb3drw@...
 

 

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?

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.

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,

Re: PCB etching

Excellent Dave, I hadn't seen that process. Will give it a try.  On the subject of pores in the toner, I have had those also.   Marshall eliminates those by opening the jpeg in Adobe with a white background and saving it back out as a tif file. Seems to do the job well.

Thanks for the link

After [laser jet] printing on glossy magazine pages, etc. and having to transfer the image several times to get a complete transfer, I was never satisfied with the remaining copper because it always had pitting and sometimes narrow traces with a very fine break in the conductor (open circuit).

I found some fantastic materials on the internet that absolutely provides a perfect transfer the first time and additional materials that fills the teenie-tiny pores in the laser jet transfer and eliminates the pitting in the remaining copper.

Check out the materials at -
http://www.pcbfx.com/main_site/pages/start_here/overview.html

You can purchase packages of the individual materials (transfer paper, toner reactive foils [seals the transfer], and a white trf foil to apply a "silkscreen" looking image on the component side of the board to label component locations, etc.  or they sell a kit with all the materials including several sheets of copper clad material, the kit is called PCB Fab-in-a-box.

The kit does not include etching chemicals.

One good feature of this method is, if you mess up and the transfer didn't work too well, simply get some steel wool, clean the PCB thoroughly, reprint the pattern, and try again.  But if you have the correct paper and use care, you'll seldom have to redo it.
