Designing an Antenna Tuning Stub
I recently acquired a fine quality VHF antenna having about 9 dB gain. See below my initial efforts at designing a tuning stub for it. The antenna already has excellent characteristics but it only makes sense to optimize it. Please look for updating articles to come describing my work regarding getting this antenna up and running....
Feed Two 50 Ohm Antennas from One Transmitter
Wes Cardone presented at the July 2024 meeting of the Chelsea Amateur Radio Club the principles of directed energy by means of multiple antennas.

An Abused Transceiver
I will take the blame for allowing my Kenwood TM-V71A transceiver to be abused. Witness the result of my abuse illustrated in Figure 1. The DC power cord has become horribly frayed and worn. And that to the point of an imminent short! But let this be a warning to others to mind what is going...

Antenna Feedline Optimal Length for Resonance
Updated 4-18-2024 I recently discovered a YouTube video that shows how to cut an antenna’s feedline length to achieve resonance (See below). I then discovered that there are many such erroneous YouTube videos telling you that you can use “jumpers” to improve your antenna performance. There are no benefits to these practices! But this begs the...

EZNEC J-Pole Modeling (and Deep-Dive)
A Qualitative Presentation At last month’s meeting (February 2024), we introduced the free EZNEC antenna modeling software. It was a very introduction-oriented presentation that explained what it was all about. For the March 2024 meeting (Tuesday, March 12th), we will be presenting concepts relating to what EZNEC software demands from you, the user. That is, what...
Optimize the Hustler 4-BPV HF Antenna
With the help of Jim Grissom (WD8RFW), we embarked upon an ambitious program to consider if his HF vertical, 4-band, antenna could be optimized. Whether it is actually optimized or not is somewhat irrelevant although it is known that our task will optimize the antenna for its 40 meter band. Our task to to see if...
