Hi, With the stub mast mounted to the rotator and top bearing is there any need to ground this stub mast independently to the tower or will the thrust bearing/rotator provide an adequate path? We get
Yup, We are having it bad in Asia too. Having a real hard time getting tower suppliers to bid for a big comms project here. All claiming that rapid price changes make their future bids look stupid. S
Folks, A very good friend, Tony HS0ZDX, has a problem with his 2800, any help on this problem would be much appreciated. I'm not too familiar with this rotator but am thinking it might be a connectio
Is the device which comes with the 2 el 5 band lightning bolt quad a real balun or just a simple coax junction box? Looks awful small for a balun if it's rated to 1.5Kw. Martin, HS0ZED ______________
Hi, The hole for the tower is being dug. A trench will also be dug and layed with suitable coduit. This will run from the tower to the radio room entrance, about 70 feet from the tower and includes a
I think this answers the question quite well. I should have thought to ask the manufacturer, it does after all seem the sensible first step. Anyway I now feel I know what I need to know and if we acc
The hole is dug, the tower will be up in, I hope, a matter of weeks, the store room has been inventoried and normal service will be resumed soon. Amongst all the 'stuff' I have a 100 metre drum of br
I'm quite interested in lightning protection. Living in SE Asia we get large numbers of storms pretty much any time of year, now is a very active time. I'm not sure that a separate down conductor wil
Not had much chance to reply to posting on the use of CAT5 as rotator cable, work can be such a drag at times. Anyway, I have received a lot of input on this, some direct and some via the reflector.
I have seen many posts on here extolling the virtues of the SteppIR antennas. My own opinion formed after studying much of the available information is, like many, that they are a fantastic piece of
Folks, Thanks for all the great information. Really cannot complain if they are just so busy it's not easy to clear all incoming communications. Good to see a company doing that well in this great ho
Well sort of, sometimes. Trying to measure a 40m antenna today that I was been playing with couple of weeks ago and now the readings on my 259 do not agree with what I have in my notebook from before
Seem to recall somebody on here asking about towers that had fallen on way or another. On the evening of Sat 30th Oct, just as CQWW was heating up, a large broadcast tower, 185 feet, in the UK collap
This is in reply to all the great info and suggestions I received to my question about the 259B. Probably what I forgot to put in the original post can be summarised here. Running on batteries, okay
Tomorrow myself, HS0ZED, and John, W2YR, will go to the shack of our good friend Eddy, HS0/EA4BKA, to assemble and install his new 3 el SteppIR. We have allowed ourselves a couple of days to complete
Thanks Pete, that is what we figured and we will be putting the EF140 perpendicular to the SteppIR elements. In this configuration do you think 6 feet is the minimum? 73 Martin - HS0ZED I have an EF-
Thanks Joe, some good ideas. On the thermal cycling we get temperature changes of about 10 degrees C all year. Now, midwinter we see daytime tems about 27 Centigrade, nightime drops a couple of degre
I have an old SY36 that I am resurrecting for use as a secondary antenna. It looks like over the years several parts have gone missing or deteriorated beyond use. Rather than get into detail here I h
Many thanks to all for the information received to date. Looks like I have some good ideas on where to find the bits. Seems the clamps might be Hygain, they used a similar fitting on some but not all
Re the RFU-503 I have used these a couple of times and they are very easy to fit. I don't have any problem fitting regular 259's but these take me only half as long. One thing to watch for though, he
