Are their designs for 80m dipoles covering 3.5 through 4.0 preferably without a trip to the antenna? Sounds like the search for the holy grail. Some ideas: 1) a pair of dipoles with one feedpoint, on
Does anyone have the specs on the T2X for: wind load, rotational torque, weight? I am looking at some yaesu rotor specs and I see stationary torque specs too. Do I need to be concerned about that spe
It looks like the T2X can't handle a C31XR and a EF240X. The torque spec on the T2X is 3400 ft lbs (weight x turning radius). The turning radius of the EF240X is 25.1' the weight of the two antennas
Ty says... No, incorrect. It's not nearly that simple to calculate and has little to do the turning radius. It has to do with moment arm for each significant piece. You can essentially eliminate the
If a triband vertical (2m-70cm) was placed on top of a mast at the 74 foot level would it be prone to lightening strikes? Would it be better side mount it on the tower? The loss in coverage due to th
I assume that a 30m or 80m inverted vee could cause interaction to a yagi (40m-10m c36xr for example) in a similar fashion that a 40m yagi can cause interaction with a tribander. If so what is the mi
If we used a side mount, would a small 2m/70cm yagi be less likely to suffer damage than our Diamond tribander (2m-70cm)? If so, should we side mount the yagi with a very small rotator and pick the p
Concerning destructive interaction between yagis, most of the what I have heard is interaction between 15 and 40 when one is over the other. The same frequency relationships don't seem to be found be
Bob, Can you tell me more about the diverters? If the tip of the 2m-70cm were about 10' down from the yagi would that help shield the vertical? Thanks, Pete -- FAQ on WWW: http://www.contesting.com/t
What does the Rohn catalog show for the guy points for Rohn 25G at 50' at various wind speeds? I have a copy of the charts for 45G and it shows 41' on the tower and 40' out from the base for 70, 90,
Hi, Is there a convention as to whether a 40m yagi should go on the top or bottom? Is a 15' mast enough or is 20' needed? Thanks, Pete ws4g -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html
Which if any warc bands can be worked with a C-31XR and/or XM240? Thanks, Pete ws4g -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towertalk@contesting.com Administrative req
You mean total mast length or mast sticking out of the tower? It's been my limited experience that you need at least 10 feet of spacing for an XM240 and more would be better. Let's assume 40m is on t
Ken, K6DB says: My XM240 works quite well on 12 meters, without a tuner. Ken, How aout 30m? Apparently the 40-2CD worked OK with a tuner there. -Pete -- FAQ on WWW: http://www.contesting.com/towertal
I looked through my notes from a discussion on this reflector a while back and want to rediscuss it just to be sure our plans are OK. Let's assume 70' of 45G at 70mph. The flat spec is 9.5 sq ft. Sin
What rotors would be candidates for turning the C-31XR and XM240 with a 20' chromemolly mast? Thanks, Pete ws4g -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towertalk@conte
What is the latest color? I am in the process of rebuilding and have a set of light blue ones from about 6 years ago or longer. Do I need to reorder? Thanks, Pete ws4g -- FAQ on WWW: http://www.conte
I am interested in a developing a list of qualified and experienced professional HF tower/antenna installers with all the appropriate insurance/bonds/references etc. This is for a fairly small job, i
For those of you that have rebuilt KT34s, what technique did you use to clean inside the clamps. I thought of buying a round file. Any other ideas? Also, do you recommend disassembling everything on
Our club is evaluating a Hazer system vs. the cost of paying a professional to climb the tower when maintenance is needed. We are rebuilding a TailTwister and a KT34XA prior to installation. Since th
