I'm learning alot from this NG!
I have a couple of questions: My antenna (RF Systems MTA) installation
will require a 60' run of coax, which of these coaxes would be the most
efficient for SW and MW listening, RG-8, RG-8U or RG-8X?
I already have 50' of RG-8 and 50' of RG-8U but, I've noticed that
Universal Radio is selling the RG-8X.
After spending big $$$ on this antenna I just want to make sure that I
get the most I can from it!!!
I also have a Archer Antenna Discharge Unit Radio Shack Catalog #
20-021, should I use this in this installation?
Thanks in advance for your help!

Anyone of those coax types will work just fine. I just looked at that
antenna, and it seems awfully small.

200' and 70' wires, matching transformers and Stridsberg multicoupler on
HF.

Ouch, I just looked at the price of that MTA antanna! It amazes me how much
the Dutch want for their stuff.

N8KVD,

Thanks for the reply.
Yeah, the MTA is pretty expensive. Universal Radio claims that the U.S.
Govt. buys a lot of these antennas for use in our overseas Embassies
with excellent results.
Can't wait to put mine up to find out.

================================================== ======================

You're right its not very big. About 7' tall and 1.25" in diameter.
Its helically wound internally with a built in MLB. In the past Ive had up
the antennas you seem to have ,, a 200' wire and later a 70' wire with an
MLB. Without any doubt I can say the MTA outperformed my 70'
wire with MLB. With the 70' wire I had, noise ruined most weak signal
stuff, that I can get fairly easily now. I don't have the room for a 200'er
anymore cause I don't live on a double lot anymore. The MTA is one
of the most quiet antennas Ive ever used and most of the time more
signal isn't the answer, lower noise is. I think short of a true longwire
with a MLB, the only thing thats going to beat the MTA is a antenna
cut for a specific freq. IMO. You are right the Dutch want a lot of
money for their stuff. But it does seem to be pretty indestructible,
where I have had wires brought down by ice and wind. Im not saying
its the best for all occasions but its a very good compromise for
general SW listening.

Yes, it's pretty expensive for what amounts to a 7' wire and a matching
transformer. Total cost to make your own (sans plastic pipe of course)
$20.00.

Yes, it's quiet because it's just a 7' wire antenna.

That's hard to believe, as I stated above, it's just a 7' wire antenna with a matching
transformer. Nothing more, nothing less. I'd put my 70' wire, with the matching transformer up
against it any day. However, if noise is your issue, I guess what works, works.

Larry, let us know how it works. I have a 210ft longwire antenna with an RF
Systems MLB and 25ft of undergound coax... the only noise that I receive is
from atmospheric conditions... it's an awfully quiet setup at the moment.

RG-58 is just fine for receiving below 30 megaHertz. Using bigger
cable is a waste.

================================================== ========================

No its more than 7'. The instructions that come with it clearly state it is
a helically wound antenna with so much percent in the horizontal plane and so
many percent being in the vertical plane so its more than a 7' wire inside. If
it were just a 7' wire it would all be in the vertical plane. In all likelyhood its
probably more on the order of somewhere between 20 and 30' in a helical
arrangement. Whether or not its worth 200.00$ I guess is another story.
for me I think it is, its indestructable, it has withstood 70 mph winds, it has
a nice stainless steel mount making it easy to grd. right at the antenna. It is
filled with a urethane foam to keep out moisture and prevent it from making
noise when blowing around, and like you say it works quite well. And it
most definately worked better than my 70' wire with its S-1 to S-3 noise
level.
