De Komunica PWR-WD-4080 is een robuuste draadantenne voor de 40- en 80-meterband (3,5 en 7 MHz). Deze trap-dipool is ontworpen voor zendamateurs die betrouwbare prestaties zoeken in de lagere HF-banden zonder te hoeven kiezen tussen lengte of afstemming. Met een totale lengte van 26 meter, traptechnologie en een maximaal zendvermogen van 500 watt, is deze antenne ideaal voor zowel tijdelijke als permanente opstellingen.
De antenne maakt gebruik van traps (spoelen) om een resonantiepunt te creëren op beide banden, zodat je effectief kunt zenden én ontvangen op zowel 80m als 40m zonder externe tuner. Dankzij de UHF Female (SO-239) aansluiting is de antenne eenvoudig te integreren in bestaande opstellingen. Bovendien is de VSWR lager dan 1.5, wat zorgt voor een stabiele en efficiënte energieoverdracht.
Waarom kiezen voor de PWR-WD-4080?
- Werk direct op de 40 en 80 meterband zonder tuner
- Compact voor een dual-band antenne: slechts 26 meter lang
- Hoge belastbaarheid tot 500W CW – ideaal voor DX en contesting
- Snel op te hangen in tuin, veld, camping of veldstation
- Lichtgewicht en mobiel – ook geschikt voor tijdelijke opstellingen
- Voor HF-zendamateurs die efficiëntie en eenvoud waarderen, is deze trap-dipool een slimme en betrouwbare keuze.

Great course on how to improve your storytelling abilities
Format: Audiobook
Storytelling is a great way to get a point across, and most of us digest information through stories. But when it comes time to tell a story, most of us don't have the skills to make the story engaging or impactful. That's where this course on storytelling comes in. You'll get good pointers on vocabulary, body language, tone, along with deeper pointers about how to shape the view of the story and how to refine its characters. It's all very detailed but it's all very interesting and well worth it. This course will help you see how useful storytelling can be in your personal and professional life, especially if you're in a field where you have to do a lot of public speaking.

This book will make a difference in your presentation.
Format: Paperback
If you rely on Powerpoint-like presentation in your work, get Cliff Atkinson's Beyond Bullet Points. I had determined that improving my company's presentations had potentially very high returns so I started poking around the net and Amazon for resources to help. At first, I struck out with books that were supposed to improve presentations, but ended up being guides on technically how to use Powerpoint. That was NOT what I was looking for.
Beyond Bullet Points is very different. It is a philosophy about creating presentations whose purpose is to communicate a story, not dump information. Frankly, it was not intuitive for me so I had to decide to just trust that it would work. When I was about ¾ finished, I started to really "feel" what I was doing. And, to my surprise, the most unlikely people really liked the result.
In a world where most business and how-to books are nothing more that restating what you already know (or, what you know isn't true), this one is an exception. I highly recommend it!

Presentations with the audience in mind
Format: Paperback
I bought this hoping it would be a guide to creating Big-3 Consulting-style slides with fancy diagrams and eye-catching graphic design. That is not what this book is. Instead, this book is about how to tell a story with slides, using the framework of a five act drama. With this method forcing you to focus on who your audience is, what they need to know, and how much time you have to tell them (as opposed to trying to shoehorn everything you know about a subject into your pitch) you end up with a presentation that finishes on time for intelligent questions from an engaged audience.
Since buying the book I have given several well-received presentations using precisely that technique. With no words on screen there is no temptation to just read the bullet points, and the audience cannot think ahead of you and must instead listen to what you're saying. You have to know your material to use this method, but when you succeed your audience will be impressed with your knowledge of the subject matter. (If you're working in a group project and want to Blue Falcon a non-contributing teammate, try giving them a few of these slides to speak to.)
The recommended slide format is one picture and one headline per slide, with no bullet points at all. The book suggests creating Notes Pages with an outline of your talk as a handout, since the slides themselves don't stand alone. (And that's a good thing--visual aids are supposed to *augment* the presentation, not *be* the presentation.)
In conclusion, this book might not be for everyone, but it was exactly what I needed.

An outsider's view
Format: Paperback
When it comes to Cliff Atkinson's Beyond Bullet Points, I am a bit of an outsider. I don't read many computer books and, while I have worked with PowerPoint, my presentations are very simple. Since I admittedly use my share of bullet points in these presentations, I thought learning about an alternative approach would be useful. And while there are definite benefits to reading this book, it may not be perfect for everyone.
Many people use bullet points in their PowerPoint presentations; this can be a great way to organize thoughts, but Atkinson has a difference approach. Essentially, the Beyond Bullet Points method treats presentations as stories told in three "acts." Act One develops the story, Act Two develops the action and Act Three frames the resolution. Each act is broken down into scenes which provide the details. The first portion of the book explains how to work with each act; the second portion deals with the evolution from initial outline to final presentation.
This book assumes a certain amount of PowerPoint knowledge; if you want to learn about the application, this is not the place to start (on the other hand, you don't need to be a PowerPoint expert). One of the nicest things about Atkinson's approach is the way he allows presentations to be pared down to fit the time frame required: his method is designed best with a 45 minute presentation, but it can be easily compressed to a 15 minute or even 5 minute presentation. Another nice thing is that he has a website that readers can access that provides some helpful materials such as template documents.
On the other hand, Atkinson treats the issue of bullet points/no bullet points as something of a black-and-white issue. He doesn't really acknowledge that there may be a middle ground where bullet points should be used in certain situations, perhaps even in conjunction with his approach. I think it's more appropriate to view the Beyond Bullet Points as an alternative approach to PowerPoint presentations, not the ONLY approach.
Atkinson's writing style is straightforward, and like many computer books, a little dry. But as stated earlier, I am reading this book with something of an outsider's view. This is a good book, but Atkinson's inability to look beyond his own approach keeps it from being a five-star work. Nonetheless, if you do a lot of PowerPoint presentations, there is enough useful material in here to merit a read.
