I use a similar one, the locking collar is a separate ring. It is a Fafnir RCJ 2 1/16. http://www.bearingstockshop.com/docs/Marcas/Pdfs/Fafnir/13flanged.pdf 73 Peter Bob: When I installed my tower in
The AT2K is a Transmatch (t-tuner) which gives you possibly higher losses then the pi net of the linear. You can simulate the losses of a Transmatch: http://fermi.la.asu.edu/w9cf/tuner/tuner.html 73
The galvanizers do also offer Polyurethan coating after electroplating, at least here in Germany, might be a solution for sea site installations. 73 Peter --Original Message-- From: TowerTalk [mailto
That shorted stub cut for 20m has to be installed on the 20m station (station B) to suppress 40 and 15 there. On the 40m station (station A)you will need an open stub cut for 20m to suppress 20 and 1
Sorry it has to be the other way round, open stub at the 20m station, shorted stub at the 40m station, I mixed it up while writing. 73 Peter That shorted stub cut for 20m has to be installed on the 2
That stub is to stop interference from 20m, not to block 40m interference on rig B! Against 40m qrm you will need that halfwave open stub (tuned for the 40m qrg) on rig B. 73 Peter So, vy late last n
A friend of mine is using a 2x 160m V-beam on 40m. The performance is as EZNEC predicted. First he was using soft drawn copper magnet wire which he pre stretched. Stretching was not the problem as he
Itīs probably a LP1005 http://antennas.usantennaproducts.com/item/log-periodic-antennas/-lp-1005aa25-kw-rotatable-hf-log-periodic-antenna/lp-1005aa 73 Peter Make sure the booms are electrically separ
VE6FI got one, may be has some suggestions. Scroll down on his page: http://www3.telus.net/ve6fi/New%20Antennas.htm Perhaps Dons, VE6JY is the same model: http://alfaradio.ca/ve6jy/images/Log1.jpg 73
Its very unlikely that it free-wheels with that R3503 rotator which is made with a worm drive gear and chain. But I am not sure what rotator Dennis is using. Too bad that California is that far away
Hi Luciano, Look out for AlMg1SiCu tubing that is the same as 6061-T6. I build all my homebrew yagis from standard available tubing AlMg0.5Si which equals 6063-T6. With your import duties it will be
I do use the same, any tower work is done by myself. The winch is permanently installed at the main tower and with the remote control connected to my belt I can activate it from any position on the t
I use a system like that. My tower is loaded with some yagis and 46m high at the top. I feed it at the 25m level against a single sloping radial. The inner conductor is connected to the radial, the s
With wider turn spacings capacity between turns is lower and coil Q higher. Centre loading is more sufficient then base loading on shortened antennas. Silver plating of coils with cool-amp is for the
Hi Jim, Never heard about the cable not being for outdoor use. It is essential to fill the body of the plugs with silicone grease to prevent the accumulation of condensed water. Connectors may not be
Its much smaller then RG-8X, but a little larger then RG-142. http://www.caledonian-cables.co.uk/Coaxia_Cable/M17_RG/RG304.html 73 Peter, DJ7WW Does anybody know anything about RG-304 ? Its aprx .271
RG-142 inner conductor is also plated steel as all that of SAT coax is. Sheet diameter of RG-304 is 7.1mm. 73 Peter (.249) It appears the center conductor on 304 is 1.5mm = .059 inch = 14.5 gauge wir
To me others look better constructed and more powerful http://smart.antenna.it/ 73 Peter, DJ7WW Hi, Best rotators are Big Boy - PST, check them out in Array Solutions; http://arraysolutions.eestage.c
I used such on my home brew rotator. http://m2.i.pbase.com/u13/df3kv/large/21834952.Kerpen1.jpg http://m4.i.pbase.com/v3/91/283791/1/50045854.P0001095.JPG Very powerful rotators are made by Luso, two
I used that product: http://www.centa.info/?show=products&c=&nr=32 73 Peter, DJ7WW Interesting, Not being a "car guy" I've never heard of flex discs. Do you have any more info, perhaps a few links to
