The A & H booth was jammed the whole show. Obviously a lot of people are into what they are doing . DLive is awesome !

The A&H guys were awesome.  They spent about an hour talking dLive with us.

Wish I could have been there. I've got plenty to chat with them about!

Well that actually wasn't too complicated. ;D
At what point does the length of the cable going to the antenna become an issue?

I still haven't been able to log in and an email to them has yielded zero results so far.

Hello, looking to get input on RCF 745a vs Danley SM80. Currently running 2 RCF 745a but wondering if its worth the cost to eventually upgrade to the SM80s. Have been running the RCFs with 2 Danely TH118s. We just purchased 2 TH118XLs, and eventually will add another TH118XL or 2. Music is EDM and venues are 300 cap, indoor and outdoor. Using Danley DNA20K4 amp.
Do you think you will make more money by spending on an upgrade? If no, why spend the money?
Is the system you have working for the gigs you do? If yes, why spend the money?
Will you get more customers by spending on an upgrade? If yes, spend the money, if no...well you get the idea.
Otherwise, upgrade because you know you will like the possible sound improvement. :)

So real newbie antenna question:
What is the advantage / disadvantage of 1/2 wave over 1/4 wave?
What does mounting either of those on a stand look like?
Do they need to be mounted on a plate?
So many questions . . .
I have a set of paddles, but may need more options in the future.
The quick and easy answer is 1/2 wave needs no "plate" or ground plane when mounted in the air. Easier to deal with.
1/4 wave antennas need a ground plane.

Judging by the specifications of your current system,
it will function as intended with no major issues.
I, myself, am using an i7-4790k with 16gb 1600mhz DDR3 ram and 660 ti.
However, if you're interested in future proofing,
DDR4 ram on the newer CPU is almost double the speed.
If you're running just powerpoint, the old system will work, but
I would suggest getting an AMD 2700x on a 240mm AIO watercooler
with 3200mhz ram grouped with an RTX 2070.
These components should last you anywhere between 5-10 years.

Thanks Peter yes we have a few resolume, encode, gfx etc machines with 64g ddr4 and m.2 and 1950x threadripper and few other bells hot swap ssd bays these were our future proof purchases with amd saying they will keep x399 set for at least 3 gens

But figure we can squeeze at least 2 more yrs out if these 6 yr old boxes with a few updates ...  just ppt ... we ended up with 24g ddr3 ram 1070ti dedicated ssd for OS and 2nd for show files along with 1tb spinning disk for archiving.

Real pleased with the graphics card upgrade ... can only hope to get 6 plus years out of every build and stay competitive with new tech the 4770 def. Holds it's own

Just curious why a water cooler way less reliable seems based on what I've read especially on the road!?! Do you have experience with that no oc at all

I was hoping to cover up to 200' with 8-10 20's per side without delays.

8 - 10 boxes of a good line array of this size should cover up to about 200 feet.  I usually consider this the max distance for this tye of system - you can certainly hear it well beyond that but the quality drops.

To me the HDL20 is amazing value, but offers very ordinary performance.  The HDL30 uses a larger compression driver and has a flat phase response over the vocal region.  This allows a lower crossover frequency and better pattern control thought the crossover region but it does get a bit narrow around 670Hz.  The flat phase response also improves intelligibility and the separation between instruments.

You can easily hear the difference on this video clip.

HDL20  Vs HDL30

If you want to have a look at the GLL files for the HDL20 & HDL30 you can see some of the issues around the crossover frequency (horizontal pattern).  In comparison the dB Tech VIO and Adamson S10 are almost perfect though this region.

Great to know. Thank you for the follow-up.

When we talk about half-wave antennas, we are typically talking about a "dipole" antenna. If you were to remove the plastic jacket on most half-wave antennas, you'd find two separate equal-length elements inside, each half the length of the antenna. Electrically, connection to these elements are made at the centre of the antenna (even if the BNC connector is on the bottom). These two opposing elements make dipoles complete antennas that can do their job all on their own.

For all sorts of physics reasons, a dipole can often be thought of as the default antenna designs  (so much so that other antenna designs are sometimes described in relation to how a dipole would perform; this even has it's own decibel unit of dBd). Most paddle antennas (but not helicals) are variations on the basic dipole (the D in LPDA stands for Dipole).

A quarter-wave antenna is, arguably, a bit of a hack. If you remove half of a half-wave dipole, what you're left with is a quarter-wave antenna. You have a single element that is end-fed. This is really only half an antenna, and if you suspend it in mid air at the end of a cable it will likely perform very poorly, but we can simulate the other half of the antenna by providing a ground plane. A piece of metal connected to RF ground near the quarter-wave antenna emulates (with some efficiency loss) the missing half of the dipole, and creates a complete antenna. In a pinch, if you need to get a quarter-wave antenna up in the air, you can supply the other half of the antenna in the form of a counterpoise, which can be as simple as a piece of wire hanging down from the antenna and ties electrically to RF ground at its base.


Such great info.  Helped to fill in some gaps in my knowledge base, which i always appreciate.

UGHH ! Frustrating. Akin to a menu makeover at a fave grub hub. Harder to adjust for this senior.
