Gary, What proof can you present to verify that your tower(s) have never been hit? i.e. They have only been up a short time (1 day or so). You have been home every day, awake every hour since your to
I had earlier asked K4FMX for proof that his tower(s) have NEVER been hit by lightning but Gary is unwilling to share that information. Then a second question entered my mind "why would Gary mount a
I would not reply to such a question either, it would be a fool's errand. If you can't support your absolute statement(s) with good experimental results, good theory, or good experience, then one sho
Thanks Gary for the information. Yes, I agree that Roger, K8RI is a creditable source and in many areas. However, I am still waiting for an answer to my question to your statement about knowing that
Gary, You have convinced me that I am wasting my time as you are unwilling to share how you know that your tower(s) have never been hit by lightning. No point in 'beating a dead horse'. I will REPEAT
The formula for calculating the 1/4 wave length of a wire dipole is 234/freq. As the diameter of the 'wire' increases the length of the 'wire' decreases for a set freq. Is there a factor that can be
There are still too many 'List Bullies', chronic complainers, or those who are too lazy to use the delete function. If you don't like the topic, Delete It! and move on. Just because YOU are not inter
Hill Radio's current price for a TB-3 is $100.32 and for a TB-4 is $117.48. Doug Howdy -- Here are some new parts I don't need: 1 BPC45G Concrete base plate w/pier pin $120.00 1 BPL45G Top plate $190
Thomas, lightning strikes. Are there any devices that will prevent ALL lightning strikes forever? What you need is a control setup to compare to the devices you tested. The devices tested may or may
I don't understand why anyone is still using a two wire tram system. A single tram wire works superb. I use a similar set up to Jim's and others hanging the antenna below the single tram line. To att
You should always use rope element dampeners to prevent the element tips from vibrating, breaking and falling off. Good insurance. Doug/VA5DX 1. Pros and cons on the rope element dampeners? _________
The topic about guying a self supporting tower has been discussed here before. There seems to be an unlimited supply of misinformation on this topic. FACT...self supporting towers can be, have been a
Two things that need to be considered What is the safety factor in the tower design...sometimes a pretty illusive number. Suppose I design/'engineer' my towers to withstand say a 200 mph steady wind.
I disagree. I have run 40m yagis at 60 feet from several different locations and found them to work well for me. When I was living in northern British Columbia I managed to work Bouvet on 40m with a
Dave, Have you ever operated 40m from the northern latitudes? Anecdotal results from a QTH in Arizona are irrelevant. Have you ever used a 2L 40m beam at 60 feet? Doug/VA5DX I disagree with your disa
Below is the best method. I have used PVC tubing as a ram rod with good results. Doug/VA5DX A method I've used with excellent results is to lubricate the aluminum tubes as best as possible, then hamm
It should be obvious that un-authoritive or is it un-authoritative Gary's laws of physics don't apply. And thanks to Bob for doing the 'leg-work' to put another Tower Talk myth to rest. Doug/VA5DX We
John, Would you share how you determined that the damage was caused by lightning strikes and how you eliminated other causes for the damage. What brand/make of rotators were damaged? Other than the p
I have successfully used 1/2" poly rope for years as a tram line to haul antennas 85# and under up to the 120 ft level. Doug/VA5DX The advantages of good 1/2" double braid rope for a tram line: 1) Pl
I have a complete, never installed, Hygain Quad that I will sell all the parts. E-mail me direct if you are interested and I will dress warmly and find the parts (part # would be helpful) inside my '
