Straight internal cable mods on Ambient Quickpoles


Recommended Posts

I have an older QX5100 that came with internal cabling when I bought it used in like new condition.
I began to like straight internal cabling for various applications but this still brings disadvantages.
Most annoying is the cable management, when you have a TX on the bottom of the boom, but also noise when the cable is bouncing in the boom when fully expanded.

Since the cable that came with it got stuck a lot, mistreated and crincled the boom needed a new cable. The boom was also on a beach catching some blowing sand and it was time for some new velours as it also started to squeak with heavy load.
As all that maintenance was due anyway, I've asked a friend to print me some washer like disks that keep the cable in place.
They do not eliminate cable noises inside the boom as much as expected, but still a bit. What they do well, is guiding the cable when it is pushed out during collapse. I still have to see if the disks hold, but I wanted to share the project with you, even if it turns out to be a failure.

Cable bounce in the tube vs TX at the mic end of pole. I've wondered how much margin there is for serviceable improvement here too. I was hoping to see a picture of the cable in situ. A light cable would be quieter and keep overall weight down but unless it's made of NASA grade, Unicorn Starquad not sure it would last long in this context. Could woven cable sleeve give a light cable more working life AND cushion the bounce of the cable in the tube?

IMG_20220616_125439.jpgWell here is the current state in situ. After 1,5 days, I think only the lower two disks have an effect.

It is indeed a starquad Belden 1804A. I've made my experiences on how to treat the cable well. Eventually, I'll have it on a retractable reel. I've been thinking of cotton sleeves, but I think the damping effect is minimal and the stiffening effect would be a lot better with some plastic. But both make the cable thicker, obviously and I might eventually implement a retractable reel, that will prevent the cable hitting the boom issue.

Some minor update:
I found a supplier with self configurable retractable cable reels including a slipring and spring. They where kind enough to send me empty samples with preinstalled springs.

I've ordered 2 each of the 1816 and the 1806 (for a ridiculous amount of shipping cost). And played around with Belden 1804a and presumably some Mogami W3031 I had around. The locking mechanism seem rather useless or needs to be improved, but I won't need it anyway fore my purpose and it can be left out for a permanent tension configuration.

The 1806 retracts a bit over a meter of the Belden cable. Not enough for my purpose. The spring however seems to have a lot more potential.

The 4 core slip ring (I've used only 3) worked without audible constraint.
The 1816 seems to just fit my needed 3 meters. I have not fully assembled this yet, but I might even go for the thinner W3031 as the reel will host way! more length.

Installing the 1816 retractor with W3031 gives impressive results. Its been on 10 weeks of shooting and booming with this is incredible.

Cable wiggle is significantly less due to the permanent tension and the disks/washers.
Cable wiggle takes only place at the top section, and not during action, so next time I'll service this, I work something around the cable in the middle of the top section.
The center of gravity allows for 1 handed situations with an MBT40S and a far expanded boom. This is somehow a really new feeling and offers completely new possibilities. My back likes this A LOT.
