The cost is about the same between a 4 SQ using full size verticals and a Comtek box vs. a F12 (or M2) dipole w/relays at 175'. For those that have one the other (or both?) or have used one can you c
sorry - for 80/75. g. The cost is about the same between a 4 SQ using full size verticals and a Comtek box vs. a F12 (or M2) dipole w/relays at 175'. For those that have one the other (or both?) or h
Alright .. .the consensus was to go with a 4SQ (over a dipole at 175'). The dipole actually shows more gain and a lower angle (with gain) than the 4SQ BUT - and it is a big one - it has a strong lobe
I am sure this has been covered many times over... if there is an article or three please let me know the url... meanwhile: I have read many times over how people REALLY seriously overload their towe
I am interested in the new F12 Sigma280S 2 el 80. The new design is suppose to be more efficient than linear loading... it has center loading and T bars. Anyway - anyone have one or know of someone t
I purchased a used RTS system for R45 tower about 5 years ago when out east... I believe I have all the components but am not sure - one thing I AM missing is ANY documentation. .. can anyone help? I
I am in need of 14 sections of R45 and the misc install parts. Located in SE AZ (near Sierra Vista). Hoping to find something in the AZ area. Gary Myers K9RX _________________________________________
hello... you had posted on the TowerTalk group last year an interest in the F12 80 meter dipole... I was wondering if you went ahead with the purchase and if so how did it work out? I am interested i
My plans are to put up ~134' R45G with the top ~93' being above an RTS rotating tower rotor with guy rings... antennas will be stacked thus the tower will be heavily loaded [we are in a 70 MPH zone h
in addition... while thinking about the conclusion of K7NV's tower stress analysis I wondered why I have never heard of a tower failing due to the BASE rupture or anything related to the base! If ind
I have read all the references to this antenna over the last 7 years or so... seems like an inordinate amount of problems regarding tuning. I am thinking of 2 of these stacked at about 120/80... but
I had twice responded to the F12 group on this and for whatever reason neither made it there... try McMaster Carr. They have what you want on page 1350/1 of their catalog 111 (viewable online). Great
write me direct and provide a fax number - I can provide their drawing via fax. g. _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wirele
Any considerations for the "right" psi rating for the cement on a tower? Standard years ago was 3000 PSI but my local area is doing 2500 as standard... does this make any difference since this is com
My question was more from an engineering point of view... the fact that Rohn "calls for" this does not really or necessarily address the question. It may well be that was the standard then as well. S
I see phillystrand is still being hawked as the best overall solution for guying where antennas will be along the length of the tower... but I still prefer good old fashioned steel. The reasons - muc
I will see if I can find it again - I may well have done him an injustice to quote without the reference. I would however respectfully disagree with your assessment - about being dead wrong. The poin
Sorry Bill... I guess I look at it differently.Not to drum up more comments about patterns and such (which I will live with better than a tower coming down) but in my opinion, no disrespect meant at
I knew someone would have to be offended.... my apologies as an offense was not intended. Funny that you felt "comfortable" with Bill's statement about "cheaping out" when it was directed at those in
I see - i understand. Thanks for the clarification. I was not being as defensive (ok - a little) with the statement as I was making sure others reading the thread (and considering these issues) were
