Antennas! I've always been fascinated by antennas - broadcast, ham radio, maritime, etc., it never mattered as long as it was an interesting array! So, as time permits, I'll post pictures and descriptions of various antenna systems that have caught my interest for one reason or another... |
First some calculations...

Nick's 14,267 Foot J Pole!!
On August 14, 2005 I thought I'd climb a 14er to get back into shape after a few days of rain throughout Colorado. I completely forgot about the annual Colorado 14er Amateur Radio Event where "Ham" radio operators work each other from the 54 14,000+ foot peaks around our state. However, as luck would have it, I encountered Nick (N5PRP) and Dawn on the 14,267 foot summit of Torreys Peak operating the event! Nick built the 2 meter J pole out of copper tubing and painted it white - it was securely anchored on the summit, having been moved there from Grays Peak about an hour or two earlier. Nick and Dawn were very gracious in allowing me to operate their station using my own call sign - thank you Nick and Dawn!!

I took this picture of a fun little hand-held satellite antenna that my club (CQC) uses on FIeld Day each year. This photo is from our very wet and rainy Rampart Range site at the end of June, 2004 - that's my 1993 Toyota just to the left of the antenna... |

Some of my previous antennas:
 My first tower, way back in 1974, age 18 and not too safety conscious... (Photo by Kendall, that's his right knee!) |
 In 2002, at age 46, I started using my climbing harness (Definitely Not recommended!!) - Photo by Tami |
 Looking down the support rope of my Green Mountain dipole - It's about 1/4" diameter (.635 centimeters) |
My old Smoky Hill QTH:
For two decades we lived near Cherry Creek Reservoir, southeast of Denver. Out there, I had 2 meter coverage from Cheyenne to Limon, Pueblo and most mountain communities on the east side of the Continental Divide. HF Coverage, with low power (I usually ran about 3 Watts) was excellent - all of this was achieved with 3 little sections of tower that kept everything about 30 feet above my backyard. Now I live in the foothills, west of Denver, so coverage isn't nearly as complete. Here are photos of my old antenna installation - boy do I miss it!

My brother-in-law Kendall, AA7QC, put up this B&W AC5-30 Folded Dipole. It's about 20 feet up and bent at a 60 degree angle making it a bit directional off the short side or Southwest. It covers 5 to 30 MHz continuously, without a tuner, and is fed with 50 Ohm coax through a built-in balun. It's overall length is 65 feet. |

My poor wife-to-be and I, back in 1975, took this photo of WWV's transmitter site in In Fort Collins, Colorado. I haven't been back since, even though I live in Colorado, so I have no idea what they're up to nowadays. Nevertheless, I did create a page of time in a feeble attempt to disect that heady little subject... |

Aren't parabolic reflectors fascinating??!!

 Carnarvon Shire, Australia |
While traveling through Western Australia Tami and I stopped in Carnarvon Shire to look at this 33.5 Metre dish. I believe it was about that time that they were hoping to convert part of its use to SETI but I'm not sure... |
