Building a new antenna at N6QW ~ Part VI

Additional evaluation of the H950 Mast


In the dark ages (over 50 years ago) while I was in high school taking the mandatory second year of Latin studies, I can well remember telling Miss Bushnell (the spinster Latin teacher) about how useless Latin was as a language and once the class was over would never use it in my lifetime. Miss Bushnell must be really smirking these days (hopefully from heaven)  as I attempt to use Roman (Latin) Numerals to order my blog posts. This says much for the old adage "Never Say Never!" I better end this thread soon as I am not sure what comes after X (Arabic 10).
 
Along the way I did learn about the "24 Hour Rule". Sometimes it is best to wait at least 24 Hours before making any important  decisions. Hopefully such a passing of time removes some of the emotionalism from the decision and adds a strong measure of logic to the mix.
 
The Never Say Never and 24 Hour Rule factors have caused me to rethink some of the concerns I have about the H950 push up mast and to come up with an alternate plan for the support mast and installation process.
 
  • My original plan was to remove the small concrete base that is now supporting the fiberglass mast. If that is removed and the H950 mast installation is a failure then I now have a problem of having No Antenna while I further resolve an alternate mast solution. Much effort went into finding dead center of the current base and the house bracket alignment. I might not be so lucky with the H950 and thus an additional concern.
  • I do my best thinking while I sleep and last night, while I slept, it came to me. Why not use the current base as a part of the H950 Mast install. In it current condition the concrete base having just a stub can serve as a temporary the base for the H950 (sans the clevis assembly). Now the H950 can be slipped over the stub and then affixed to the existing bracket assembly. At this point the mast only weighs about 34 pounds and this can be done without any extra hands or equipment. 
  •  
  • This achieves two purposes: 1) I can hand raise the H950 mast and get a better feel for its mechanical rigidity and 2) when raised to 27 feet allows the determination of the guying lengths and to evaluate the impact of the guys. The real bonus is that it preserves the original base assembly so that if necessary the current fiberglass antenna mast can be put back in place fairly easily.
  • Since I must wait a month for the beam to arrive, if this temporary H950 install works then I have the option of using the 20 Meter EDZ antenna with the Rohn mast and that will also be a part of the additional guying.
  • My brain while it was working on the problem, also came up with a way to pour the new base around the existing base so the clevis assembly can be refitted to the mast and the new concrete poured around the existing base with the mast installed. This will allow straight and true alignment of the mast.
  • In sum these new thoughts about the H950 enable me to make a measured evaluation of the H950 mast. Assuming this works the mast would be "pushed up" in place using some hired help to assist with that task.
  • I  also looked at the spider beam mast and concluded that I would be spending an additional $450 to essentially have the same concerns regarding rigidity and the erection process
We now have a plan for further evaluating the H950 that enables me to have hard data on its suitability while providing an option to go back to the fiberglass mast.
 
Stay tuned de N6QW.

2019 ~ What is the simplest homebrew SSB Transceiver that can be built?

4/27/2019 The Future of our Hobby is Here! Forget those simple rigs with homebrew crystal filters, cranky IRF510's and the analog VFO's. SDR is the wave that is building strength just like a Tsunami. With the Soft Rock V6.3 SMD Version + RRPi2 With the Omnia SDR and RPi2 Pete N6QW How Simple & How Cheap can you  build a Homebrew SSB Transceiver? 4/26/2019 --- I just converted my websites from an obsolete Windows Based Server with GoDaddy to their cPanel (Linux). This was a cost issue as a one year renewal of the Windows Server would buy three years on the cPanel. GoDaddy is discouraging the use of what they call the Obsolete Windows System. So I had to migrate and reload the whole pastapete.com, jessystems.com and the n6qw.com sites to the Linux based servers. Some files and links got lost in the translation --so you might not be able to see everything! Essentially I have  to open every link to verify that it works --that may take some time

New Technology for 2020 ~ The Hermes Lite 2.0 SDR Transceiver

  The Hermes Lite 2.0 SDR Transceiver. November 7th, 2020 ~ It's Settled! It is done! The stain of the Trump era is soon to be removed! Thanks to all who voted. The Voice of the People has been heard.  Congratulations to President Elect Biden and Vice President Elect Harris. Pete N6QW November 3rd, 2020 -- IT WAS THE MOUSE   We all know this is Dump Trump  Day. Go out and vote! It was the mouse! Back in 1999 I stupidly was one of the very first to purchase a Ten Tec Pegasus. Never buy the first batch of a new model.  Touted as the world's first computer controlled radio , actually I think the Kachina 505 was really the first. But the Pegasus was fraught with problems including a trip back to the Smokey Mountains. I was using an older Windows 95 machine to control the Pegasus and that may be a co-conspirator. Well after many calls to TT -- finally someone who has some smarts told me: Fix your station ground, Make all leads short and Buy stock in a ferrite bead company. I did all

The Next Project Updated 10/10/2022! The rubber has hit the pavement!

The Next Project... A 2022 Transceiver. 10/10/2022 My Apologies. It is with regret that I will be terminating any further work on this project. My caregiver duties have over time become a greater time sink and it is almost impossible to build something working only 10-15 minutes at a time spread out over a day. I apologize for not getting it from design ideas to complete hardware. Most likely I have built the last transceiver I will ever build. Thanks for riding along. My website https://www.n6qw.com/  has the pdf of the postings and I will leave this blog page as is. 73's Pete N6QW 10/05/2022 Still Alive! Regrettably my caregiver duties have overtaken any free time so not much progress. But I am hopeful yet this week I will cut at least one board. A PSA from N6QW.  Think of it like Mary Jo has a "crink" in her back and unable to get in the backseat of the 57 VW Beetle. A bit of a setback but not forever.  Seems like the hired caregiver had a small emergency and not able
