[K3PZN-List] presentations

[James Nitzberg]

Hi Mark,

This is a GREAT topic, and one of my personal favorites.  

You might be surprised how well your wire dipole would work at the right height (perhaps you already are).

You are correct that most folks place one tribander (or more bands on one antenna) at a compromise height because of cost and land constraints.  

There are also different heights for different objectives, and of course the lower in frequency you go, and the more DX you wish to work (assuming your goal is DX), the higher you generally wish to get the antenna.

Some questions for you to answer before I form some broad recommendations and suggestion for you are:

1.  What is your goal?  To work DX?  USA stations?  Rag chewing?  Contesting???  Give me some idea of your interests.  CW or SSB?  Digital modes?

2.  How much land do you have to use for your antenna installation?

3.  Do you have any tall trees > 60 feet tall that you are willing to use for wire antennas (i.e. wire yagis, etc.)

4.  Are you open to using a directional array of phased verticals on 80 & 160 meters?  Do you care about 80 & 60 meters?  
(A better question is: What bands do you wish to operate and/or optimize?)

5.  If you are hoping to do well on 80 & 160, do you wish to utilize specialized receive antennas (Beverages, loops, vertical arrays?)

6.  Do you have any aspirations for running more than one simultaneous transmitter, or having one operator control two radios at once (SO2R)?

And last but not least....

What type of investment are you willing to make in dollars, to achieve your radio goals (a range is a good place to start, i.e. $1,000 - $5,000, $5,000 - $10,000, etc.)

If you give me this type of background on your goals, I can begin this dialogue over the reflector, or I can sharpen it and try to make an interesting 45 minute presentation
with some examples of existing stations out of it.

Andy-
I have a question that may be a good topic.  Or the answer may be so simple as to not warrant an entire meeting.

My current station consists of a radio, and a wire dipole.  Pretty basic.  The wife is allowing me a tower at our next house (moving in a year or so now that the kids are all out).  So I need to decide how to select the correct antennas.  From what I read in “the books”, proper beam height is 1.25 wavelengths.  But looking online what I see are many stations with a single tower/antenna, a multi band yagi at one height.  I assume that is a compromise for cost and space.  But I am not sure.  Is there another reason I am missing?  And sometimes I see stations with a tower with a beam at a height other than 1.25 wavelength.  Why? Am I missing something?

A talk on the “best” method of setting up a station using a tower with beams, what kind of beams at what heights, and what other types of antennas (such as 80M and 160M, receive antennas, etc) would be great.

Then another talk on station equipment.  Such as antenna switching, automated band selection and sequencing to power down pre-amps, receive antennas, etc, use of filters (just for contesting/multiple transmitters at once?  Or helpful for reducing noise for DX)?  Other types of helpful electronics, etc.

I know those are pretty broad topics, but any help would be very useful.
