Radio Dad joke alert...

Brian Richman
 

As you may know, I work in the technology industry particularly I work for the IT department of a major university. One of the things we do is to track uptime and availability of software. On a conference call this morning one person mentions maintaining "five nines" of uptime (99.999%).

Maybe the coffee hadn't kicked in yet, but for a moment, I truly couldn't understand why he was giving a signal report in the middle of this conference call.

ICOM IC-9100 and BigIR Mark IV Vertical Antenna, 80m-6m For Sale

dafuser
 

I have an ICOM IC-9100 radio with the D-Star module installed for sale. It comes with original boxes, manual, and an ICOM mic. The radio was been sitting in its box for the past couple of years as we lived in an HOA controlled development where no external antennas were allowed. the radio has only been used for D-STAR and has had about a dozen HF SSB QSO's.

I also have a BigIR Mark IV Vertical Antenna 40m thru 6m with the optional 80-meter add-on. This antenna has never been installed and is still in its original box and has everything necessary to assemble and install. The antenna is 43 feet tall and has the moveable internal metal tape the tunes the antenna for the various frequencies. I'll throw in a DX Engineering radial plate with the antenna.

Asking $1500 for the radio and antenna if sold together.  If sold separately,  $900 for the radio and $900 for the antenna.  I'm trying to sell the radio and antenna because they're not doing me any good sitting in their boxes. My information is good in QRZ.com and my email address is na5aa@...

Wayne,

 

That is interesting indeed.  Based on what I’ve experienced (which parallels Ed Fong’s comments on the subject), the N9TAX performs okay on 2M but not as well on 70CM because it is reportedly only working 70CM harmonics.  The N9TAX also does not perform as well as Ed Fong’s dual band models do on both 2M and 70CM.  If I’m not mistaken, I recall that Walt (W5BNK) replaced his Diamond X50A dual band antenna with a $36 Ed Fong DBJ-1 (ham) dual band base antenna because the Ed Fong performed better than the Diamond did (Walt, please correct me if I got that wrong).

 

If you have an RF Signal Strength measure of some kind, it would be a great experiment to compare the 2M and 70CM output of the N9TAX with the $36 Ed Fong DBJ-2 (ham) dual band roll up antenna.  I also have one of each and I’m willing to employ them for the experiment if you’re interested.

Subject: [wc5c] N9TAX Slim Jim Antenna

 

I was working with my antenna analyzer today. I have an N9TAX dual band (2m and 70cm) Slim Jim in my attic. This antenna sells for $33.44 shipped with a 16’ cable and PL-259 connector. Other cable lengths and connectors are available.  I ran a 2m sweep to look at the SWR. The bandwidth is typically defined as the 2:1 SWR points. As you can see from the graphic, this antenna is 1.39:1 at 144MHz and 1.14:1 at 148MHz. The analyzer I was using does not go to 70cm so I don’t have that information handy. The SWR is actually quite good for the entire 2m band.

 

Ed Fong also sells a similar antenna. I have one so I may try the same sweep on it and compare them.

 

Also, the SWR is NOT an indication of gain, or radiation angles, etc. Those parameters depend on many things including height, nearby obstructions, mounting technique, etc.

 

The graph is from AntScope2 using a RigExpert Stick analyzer.

Re: N9TAX Slim Jim Antenna

Wayne Morris - AC5V
 

 

I think we would need to use the same transmitter radio (frequency/modulation/power), coax, location/position, mount, etc.

 

We should test both transmitting and receiving.

 

We need to plot the data. If we to a rotating test station, we could do an azimuthal map.

 

The antenna could be a vertical dipole to have dipole referenced data.

 

We should test as many antenna samples as we have available.

 

Directional antennas could to forward gain, f/s ratio, f/b ratio.

 

We should document the whole thing and write an article for QST.

 

How long is this going to take?

Interesting Jon.

 

Would the fact that the Yagi antenna was oriented horizontally but the receiver/testing antenna was oriented vertically make a difference?  In other words would the Yagi’s transmit pattern have been the same since they were only 18’ apart or would it likely have been different if both were oriented the same way?

Sounds like CLub Project time. Nano VNA and build us an Antenna Range. :)

Wayne,

 

That is interesting indeed.  Based on what I’ve experienced (which parallels Ed Fong’s comments on the subject), the N9TAX performs okay on 2M but not as well on 70CM because it is reportedly only working 70CM harmonics.  The N9TAX also does not perform as well as Ed Fong’s dual band models do on both 2M and 70CM.  If I’m not mistaken, I recall that Walt (W5BNK) replaced his Diamond X50A dual band antenna with a $36 Ed Fong DBJ-1 (ham) dual band base antenna because the Ed Fong performed better than the Diamond did (Walt, please correct me if I got that wrong).

 

If you have an RF Signal Strength measure of some kind, it would be a great experiment to compare the 2M and 70CM output of the N9TAX with the $36 Ed Fong DBJ-2 (ham) dual band roll up antenna.  I also have one of each and I’m willing to employ them for the experiment if you’re interested.

Subject: [wc5c] N9TAX Slim Jim Antenna

 

I was working with my antenna analyzer today. I have an N9TAX dual band (2m and 70cm) Slim Jim in my attic. This antenna sells for $33.44 shipped with a 16’ cable and PL-259 connector. Other cable lengths and connectors are available.  I ran a 2m sweep to look at the SWR. The bandwidth is typically defined as the 2:1 SWR points. As you can see from the graphic, this antenna is 1.39:1 at 144MHz and 1.14:1 at 148MHz. The analyzer I was using does not go to 70cm so I don’t have that information handy. The SWR is actually quite good for the entire 2m band.

 

Ed Fong also sells a similar antenna. I have one so I may try the same sweep on it and compare them.

 

Also, the SWR is NOT an indication of gain, or radiation angles, etc. Those parameters depend on many things including height, nearby obstructions, mounting technique, etc.

 

The graph is from AntScope2 using a RigExpert Stick analyzer.

Re: N9TAX Slim Jim Antenna

Interesting Jon.

 

Would the fact that the Yagi antenna was oriented horizontally but the receiver/testing antenna was oriented vertically make a difference?  In other words would the Yagi’s transmit pattern have been the same since they were only 18’ apart or would it likely have been different if both were oriented the same way?
