Antenna Part Deaux

June 24, 2012

G5RV Jr. Back in the air.

Today I put the G5RV Jr. back up. As you can see above the feed point is in the clear! It wasn’t before. Hopefully the clear feed point will work out much better for operating QRP. I knew the leaves and branches were reducing the radiation because the tuner settings changed from winter to summer. Although I have not checked it yet I expect to see dramatic changes in the tuner settings now that the tree is gone. If you look at the photo below you can see a wide shot of the antenna. The legs go over the tops of two Pine trees and are tied off. on the left of the picture the end is secured with a three foot bungee cord. It allows a little give with the wind (and falling Mulberry trees) and also has about 6 feet of the UV resistant end rope in a loop and secured to the fence. That way if the bungee breaks, the antenna doesn’t come all the way down. The darker part of the feed line is 300 ohm window line. At the edge of the garage  roof it switches to grey RG-8X to the shack. By the way the Jr. is a converted WA2NAN Trutalk 204′ model as I don’t have enough room for that size. It is well constructed and has been in the air for 5 years at 3 different locations. In this photo you can also see the stump of the Mulberry tree and remaining sawdust.

Wide Shot

The right side of the antenna is though the top of a substantially larger Pine tree which is also on a rise in the yard.  Below is a a street view of that tree with the antenna tied to the gutter. I know you can’t see it but that’s the idea isn’t it? So you get an idea of why the antenna in the pictures has a slope to it.

I will post some reports when I give it a try this week. I do have plans for a 31 ft vertical support for an 80 and 160 Inverted L for fall. When it is installed I will have coverage for all HF bands.

The Antenna Gods smiled upon me today!

My HF antenna got stretched a little today. The G5RV Jr. runs from the corner of the second story roof over a Pine tree then a Mulberry tree and then another Pine tree and is tied off to a chain link fence.  The feed point is in the middle of the Mulberry tree. Or at least it was until today. When I walked through the house this afternoon I noticed a low hanging branch and out I went to investigate. Well it was more than a branch, it was about half the tree. The Mulberry tree belongs to the neighbor and it had split about 3 foot down the middle. He is going to have it taken out. That is a wonderful thing for my antenna. It was not damaged in the fall. The bungee cord I use to maintain tension stretched a bit, it was time to replace it anyway. The best part about the tree getting removed is that the feed point and vertical component will now be in the clear. In the winter the bare tree didn’t seem to affect the radiation. The leaves seemed to affect it during the summer as you would expect. So even though I wont be on HF for the next couple of weeks, my signals should be a little better when I return!

Dayton Hamvention Comedy Bits

June 5, 2012

One of the things I enjoy the most about going to Hamvention with my group of friends is the funny things that go on. Kennie KC8BBU, Mark KB8RBT, Missy KB8VFK, and Doug KD8EZD are great friends. We have been going to Dayton as a group for about 6 years now. It all started when I lived within a few miles of them in Southern Ohio. When I moved away we continued the tradition and it became a reunion of sorts each spring.

Anyway as with most groups of friends the ribbing abounds and it never stops. Of course someone falls asleep in a chair at sometime over the weekend. This year it was Missy. Of course I took a pic with my cell phone. I posted it on Facebook for her birthday with a comment about getting old. My 50th is coming up in a few months so there will no doubt be retribution!

One of the guys made a comment about not being able to find the flush button in the Port o let. He was quickly instructed to look under the horizontal cover that was below him. Of course he couldn’t find it!

A couple of weeks before Hamvention, Pam my YL was trimming the Ivy at the back of the house. She accidentally cut a section of RG-8X that runs to my VHF/UHF antenna. I told her we would be able to get some replacement cable At Dayton. On Friday Doug bought a spool of 300 feet of 7/8′ Heliax. When Pam showed up On Saturday with me she was told that they had bought the replacement cable for her. Of course her eyes bulged when she saw the size of the cable. The running joke all day was how we were going to lift the spool so we could put it on top of my compact car for the ride home.

Kennie had some PC’s on the flea market table without Hard Drives. One brilliant person after looking at them ask a question. “What operating system do these have?” The ensuing explanation of how a computer works provided a whole weekend of snappy comebacks “yeah but what operating system do they have?”

The best bit of the weekend I got second hand. The group was on their way home on Friday night. As they passed a local dairy/restaurant operation. Mark asked what they were going to have for dinner. Doug very dryly said that he wanted Ice Cream as he pointed to the dairy place going by. The rest of the way home Doug commented on how he really wanted ice cream. When they passed a small Ice Cream stand near home later, Mark almost put Doug out of the vehicle as he brought it up again. We ended up at the original place on Saturday evening for our group dinner. Of course we had the delicious Ice Cream! Check out Young’s Jersey Dairy if you are interested.

Good friends make a hamfest so much better!
