Last year I purchased the 144LFA8, 8 element Yagi for 2 metres from EAntenna but it’s been in it’s box ever since.
That is until now. It’s May 2021 and we have thunder and lightning so with the mast down, I have decided today I am going to build it so I can replace my 5 element one.
In this post I will show you how I built, tuned and installed the antenna on my mast.

MiniTiouner hardware was designed by Jean-Pierre F6DZP and is a DVB-S/S2 USB receiver that works with MiniTioune software. It covers 143MHz to 2450MHz and was designed for use by Amateur Television (ATV) operators.
Like other amateur radio operators I want to use the MiniTiouner and software to receive transmissions from the Es’hail 2 QO-100 geostationary satellite.
I built my MiniTiouner (phase 1) in January 2019 but due to work commitments have just got round to using it.

It’s 11th March 2019 and I’ve just added an OLED display to my MiniTiouner. A simple, low cost, low effort addition to an already brilliant piece of kit.
This blog post shows how I did it.

Last year I purchased a Solent 23cm Amateur Television (ATV) transmitter. Although working, it needed a bit of a tidy up. Whilst tidying things up I decided to make a few modifications and place the transmitter in a new case too.

In October 2018 I started using a Comtech 23cm transmitter for my ATV operations. Rather than use the 8-way dip switches to tune the transmitter, I decided to work on a project to develop a rotary LCD tuner using an Arduino Uno as the micro-controller. This article shows how I did it, including the code.
For 23cm Amateur TeleVision (ATV) I am using a Comtech 23cm transmitter powered by a 13.8V power supply.
This article tells why and how I replaced the voltage regulator.
On 19th January 2017, I started the process of making a printed circuit board for my 23cm amplifier project. I was extremely pleased with the results so thought I would write an article and make a video that shows how I did it.
In March 2018 I designed and built a multi-sensor, real-time temperature monitoring and logging system using Arduino.

In February 2018 I purchased a second hand Tennamast 10m tilt over Adapt-A-Mast complete with rotator cage, CDE Ham II rotator and CDE rotator controller.
Although I saw the rotator working I decided to check over the internals of the rotator, give it a bit of a service, refurbish the exterior and clean up the connection points.

Rawlplug is my new best friend! I will be using this to secure threaded studs in brickwork as part of my Tennamast installation.
