I just put up a DXE dual beverage... the manual does not say (unless I missed it) nor does the ON4UN Low Band book say if it is important to have the end "boxes" at or near the ground. Not specifical
I had a lightning hit on one of my controllers (actually both but I was able to get the first one going again)... the xfmrs are gone - the wires bare due to a hit. I need to know what the turns confi
Hello, I was wondering if there's more reviews somewhere on this antenna system? Anyone have one that wants to comment privately? I note that Eham's latest review is 3 years old and there aren't very
I've had similar problems - my Acom 2000A would shut down on an Arc fault on 160 when I had the receive antenna (K7TJR 4 Sq) pointed towards the xmit antenna (100' vertical inv-L) that is about 300'
a similar issue to using SDR's placed elsewhere to the operator and the validity of "contacts" made by such methods... I wouldn't want to ruffle any feathers but after only being on the band for just
Hello all... please forgive me if this is a not so smart question.... I ask it because after having done some research, both with ON4UNs book and on this site Ive not really seen an answer. Several p
I just purchased a HiZ 8 element array ... and am trying to decide which way I want to go. I want a bit better performance on 40 than the standard 80 spacing provides (lobes are quite high angled) ..
Thanks Bob, 70 is what Lee use to offer ... I had a 4 sq with those dimensions (it was stolen out of a self storage unit however). I believe Lee would do cabling for either 70 or 60. My main focus is
Hi Lee, Alright - I'm convinced then. I'll do the 60'! Thanks Gary Gary and others, As I said losing 6 dB + on the 4-8 Pro by going to the smaller diameter array down to 84.84 feet in diameter will b
My planned inverted L has morphed a bit ... I modeled it it is planned as a 95 100 vertical section (depends on the amount of droop I can remove from a ~400 line from the top guy ring at 122 to a tre
Hello Bob, When Ive modeled a 160 vertical interior to an 80M 4 sq I find the vertical interacts terribly with the 4 sq. The tower would need to be broken up in to 3 sections ... not a simple task...
thats a pretty general statement! I had a 90 high inverted L with the bend supported by a tower it was only about 50 from a 143 tower ... it had ~30 100 radials under it ... and I managed to work 100
JC, Totally agree! I have a HiZ 8 element (60' side for the 2X 4 element) receive antenna ... when I model it there is BIG time interaction ... I can move the 160 meter 'T' (what I'll be using here)
Really? Well established FACT? Im quite confused then as reading Johns book it seems quite nebulous the impact of elevated radials. Doesnt seem to be a fact more dependent on location and other varia
ahhh.... forgive me if Im wrong but all of this discussion was relative to ELEVATED radials correct? It does not apply to radials on or in the ground right? If so then all the stuff published up unti
Hi folks:Iam in the process to reinstall an inverted L antenna. Due to the category 5 hurricane that passthru the island of ST.CROIX usvi i loss 2 towers and antennas.one of the towers use to support
