I have used this with LMR400 and every RG-8 like cable I can find with great success as well. I even have used this method with 9913, but I have had bad luck with that cable for other reasons. I just
For the record, I have 14 TIC Ring Rotors in operation. With more going up! They work great. I have a full size 4 element 40 meter OWA beam (25 square feet of wind load and 370 lbs) on one and it wor
Hello Tonno! At the end of the day there is probably little if any difference between the two methods you described. I opted for your choice #1 when I installed my Comtek 4 squares (two for 80 meters
This was presented earlier this year at the Dayton Hamvention Antenna forum. You can see all 57 slides about this antenna by going to http://www.k3lr.com Click on Dayton Antenna Summary 2006 73! Tim
Hello Dan: I wrote an QST article (along with K3LC and WA3FET) that described what I learned from the experiments and what antenna configuration I ended up with. It was published in the early 90s. I
Hello Dave! You might look at the photos on my web site http://www.k3lr.com under the tab of 80 meter vertical project (two phased 4 squares). I am using the HyGain Hytower as the building block for
Pictures of this method are now posted at: http://www.k3lr.com/engineering/pl259/ 73 and Merry Christmas! Tim K3LR I have hundreds of silver plated PL-259s in service at my station. They are all sold
I have used the W2DU chokes and at 1500 watts they get way too warm. I suggest the W0IYH design. I use one at the output of the amplifier and one at the feed point of every antenna. They work GREAT.

Hello Bill! I have had a full-size 4 element 40 meter Yagi on a 50 ft boom (25 sq. ft of wind load) mounted on a TIC 1032 Ring Rotor with two motors for 14 years at 120 feet with no problems. 73! Tim

Hi Garry! Check out: http://www.k3lr.com Under "Station Engineering" Click on How to install a PL259 connector It gives you a different method that I have found to work very well. 73! Tim K3LR Garry
Hi Mike! For the record, K3LR on 15 meters has been upgraded! This past summer we changed out the 3 high stack of 6 element Yagis. The new K3LR 15 meter antenna system is a 4 high stack of 7 element
Hello Bill! I would recommend either a coax choke or a W0IYH bead choke for your X7. Either of these solutions can handle the rigors of RTTY contesting without failure and will deliver superior shiel
I am looking for a low price supplier for Belden Coax Cable. Let me know if you know of one. Thanks and 73! Tim K3LR http://www.k3lr.com _______________________________________________ ______________
I have always purchased my Phillystran from Gerald, K5GW and his team at Texas Towers. Outstanding service and timely shipping. 73, Tim K3LR _______________________________________________ __________
HI Tom! After 25 years with Gamma matches and Beta match feeds, the direct 50 ohm feed (with a good choke) OWA Yagi is the only way to go. There is no decrease in gain by using a OWA design. I have c
The 0.5 dB of gain loss comes about as a by product of maximizing the gain and F/B bandwidths. When you do that it sacrifices a small amount of peak forward gain. The same issue occurs in conventiona
I think your pot may be bad. Measure the resistance from the ground between all 3 wires. 73! Tim K3LR _______________________________________________ _______________________________________________ T
