Ah I see - I have a 25AG3, which has 2 1/4" OD and a 14 gauge wall. A 2" Rohn mast fits easily inside it. If you really have a 25AG (no suffix) then our catalogs agree. Did you get it new? I remember
My brother-in-law used to have an office on the 85th floor of the Sears Tower. When the wind blew - it seems to do that often in Chicago - his pictures would lean out from the wall. Regarding the guy
Do you have current accurate information, Bill? I just googled and could not find anything since February. 73, Pete N4ZR New Articles Daily - the Contesting Compendium at http://wiki.contesting.com T
The blocking of attachments such as graphics with messages was originally based on concern that they might be vehicles for viruses, as well as the bandwidth implications of large attachments. The imp
I'm a little uncomfortable with the very small bend radius of the coax in that setup. With foam-insulated coax that could risk a short from the center conductor to the shield. 73, Pete N4ZR _________
There is a better way for at least some F12 40m yagis. My EF240S has two identical linear loaded dipoles, and I had tried the part-height tuning without success Finally, I put it up at full height an
This happens all the timeon 10, and I would presume on 15 as well. Particularly in low sunspot years, I've heard and worked Europeans on 10 at 90-95 degrees just before a real band opening. K3ZO has
I am using an active 8-foot vertical elevated at the base about 25 feet (on a roof edge) for receive-only (RBN). Would the antenna be more sensitive ifI directly grounded the case (and coax shield) t
Can we please declare (or reiterate, in case I missed it) that Towertalk is a no-politics zone? -- 73, Pete N4ZR Check out the Reverse Beacon Network at <http://reversebeacon.net>, now spotting RTTY
I'm sure this question has been asked before, probably on this reflector, but so far I've found that the level of knowledge seems to increase with time. So... If you could have one horizontal single-
After all this time I'm contemplating my first direct buried run of coax. Hence this qwuestion - how deep is deep enough? DoI need to get below the frost line? -- 73, Pete N4ZR Check out the Revers
My EF-240S with the original Alumoweld loading was up for almost 20 years, and never had any trouble with the loading wires. I did not take any special steps to prevent breaking, and they came down l
After spending a frustrating afternoon trying (and failing) to drive a single helical guy anchor for my AB-577 tower, I'm looking for a better solution. I'm trying very hard to avoid excavation, conc
The next size down is what I've been looking at, called Duckbill Anchors 3000 lb working load, 7700 lb breaking load. To be sure, not so fierce as the Manta Ray anchors, but don't require construct
I am in the process of reassembling an old F12 C3E, and noticed that there were no washers with it. Somewhere I think I recall reading that when you use split lock washers, for example with U-bolts
Does anyone have the coupler part of a VFD power meter (Radio Applications, Inc., late 90s) without the indicator unit? I seem to have lost my coupler in the process of moving to Maryland, and now th
I need a ~25-foot telescoping fiberglass pole for a K9AY loop. A lot of the poles advertised on the internet seem to be quite fragile, particularly in the top section. Any recommendations for somet
What to do when two respected references differ? ON4UN's book assumes an Inverted-L is always a quarter wave ~135 feet), while the ARRL Antenna Book assumes 165-170 feet. ON4UN mentions longer ante
(You can skip to the next-to-last paragraph if you wish; it's where the question comes in) I'm experimenting with a 40M antenna built by W1LWH, based on W7WKB's article in December 1995 QST. It invo
