Rodents love the smell/taste of new cables. I have been told that manufacturers use animal fat as a lubricant in the manufacturing process (sounds like a fairy tail but who knows?). The next time I i
I assumed it was a smell/taste thing because the danged critters only go for new cable(s) while ignoring old existing cables on the same bundle. Last year when installing some optical encoders on the
The new version Phillystran (part numbers ending in I for improved) was developed to eliminate the need for potting ends for terminations. The potting ends worked very well and are still used on size
If a tower manufacturer tells you that a 15 sq ft antenna load can be placed at one foot above the top of the tower when the wind blows 70mph then some conclusions can be drawn: The tower is strong e
When we (Texas Towers) decided to stock aluminum tubing back in 1992 I did a lot of searching for tubing sources. I found that nearly all of the amateur antenna manufacturers were using 6063-T832 tub
Here is the straight skinny on 25G top sections: Several years ago (ten or more) Rohn redesigned the 25AG2 and 25AG3 top sections to use a 2.25 inch o.d. 14 gauge wall top support tube. After galvani

A signal to noise ratio of 0 dB doesn't mean there is no signal but all noise; it means that the difference in amplitude of the signal and noise is 0 dB and that the amplitude of the signal and the n
Several years ago Rohn discontinued the BX style gin pole clamps. They were a bit fragile and failure prone. The BX style clamps were used in pairs with the P2545 12ft long aluminum gin pole. We (Tex
The advice about purchasing the telescoping masts at Lowes or Home Depot is excellent. Texas Towers does carry these for local trade but they are too big for UPS and truck freight minimum charges wil
KLM has closed their doors and all equipment and fixtures have been sold. I was told that there are some parts left and will be sold as long as they last. I do not have a number or e-mail address for
That nice color photo on the cover of the Rohn catalog showing the TH11 on the HDBX48 was taken at none other than Texas Towers by a Rohn sales director. The tower was installed in 1980 and has had a
Another perspective on this question: If you examine the guying specs for a Rohn 48ft Foldover tower model FK2548 ypu will find a recommended guy distance of only 18 feet, or 37.5 percent of the towe
