Assembling Log Periodic Antennas – Part 2

Another big lift in the process of getting the HF log periodic antennas up. With much help from Vern K9EME, the T-12 is up and initial testing shows it’s performing very well.

There are a lot of steps to do in any antenna project, and this one was no exception.

I’m completing this post Sunday afternoon, as I have had enough feeding the mosquitos for a weekend.  Pictures with brief comments (and yes, the project is not done yet):

The Skyneedle has an offset rotator drive.

 

At the Skyneedle’s lowest elevation it is obvious a few more trees need to be cut back.

Assembling Log Periodic Antennas – Part 1

Time to (finally) build the Log Periodic Antennas for the home QTH.

The big one is a Tennadyne T12.30-10HD – a twelve element 30 to 10 meter version.

Here is photo borrowed from the manufacturer’s website of a T12 on a tower (mine is going on a Skyneedle):

Assembling has taken several after work sessions.  Here are some photos:

Second ZeroFive Flagpole Antenna Commissioned

My Washington Island QTH’s ZeroFive Flagpole antenna is ON THE AIR!  Yeah!!

This has been a silly long project, with the antenna waiting for a year to be put up, then two seasons where the conduit wasn’t getting installed, the lost “virus season” and finally this season being put on the air.

Hitting bedrock and the flagpole base:

Correcting the antenna end of the conduits: https://k9zw.wordpress.com/2021/08/09/working-outside-when-the-sunshines-island-conduits/

The conduit has been a troublesome part with the route being different than originally sketched, the electrician involved being taken away due to an extended family emergency, and my foot dragging to boot.

Hmm, how to figure out where to run them inside?

Working outside when the sunshines – Island Conduits

At my Washington Island, Wisconsin QTH (US Island WI-001L) is my second ZeroFive Flagpole Antenna. On the Island we fly our flags often while in residence, but the antenna part has languished unfinished.  It has become a continued request from the XYL every visit to “please fill in the flagpole base’s hole, and fix our lawn.”

Early in virus lockdown I got someone to bury the conduits, which had sat on the lawn for at least a year. Though the main expanse was buried, neither end was done.

The radials were dug in a few weeks ago (see my previous post at: https://k9zw.wordpress.com/2021/07/18/k9zw-north-radials-for-the-flagpole-antenna/) but were left tied-off to the pole, conduit or something else in the hole.

K9ZW North – Radials for the Flagpole Antenna

With Tom K0TTC running his tractor with pipe burying attachment and Dale N6JSX helping measure, the buried radials for my Washington Island Zero-Five Flagpole Vertical antenna went in this weekend.

Unlike the home QTH the radial count is lower, as the install work was more involved, the heat was relentless and at he lowest number I was willing to initially install I decided to join N6JSX who smartly had retreated from the sun & heat.

FlexRadio 4o3a TGXL Tuner Genius Has Arrived! (Unboxing)

UPS delivered a long awaited addition to the K9ZW ham shack, arriving of course on the only day I was out of town.

I removed what I thought was the inner box from the big generic shipping box filled with packing beans, a box that UPS had roughed up a bit in transit. Final unboxing was deferred to Saturday June 19th 20201 as I wanted to put this tuner into use for some weekend work.

First a few unboxing photos:

Opened – inner box, quick start notes and of course more packing beans
