Amateur Radio Project

07/13/2016 8:45 AM

Just thought some of the "Hams" on here might get a kick out of this.

We replaced the 7/8" hard line with one that's 1-1/2" in diameter. The tower is 300ft at the top, and the antenna is at the 200ft mark. We hauled the new coax up using rope and pulley. Two climbers on the tower to do the work up there. This is in Wales, Maine. Repeater is 146.290 - W1PIG. The old coax had a splice and other issues. Performance is MUCH better now!

Nice view!

And of course I had to do some supervising and guiding the pull line!

Which has/had lower insertion loss, the "old" coax or the "new" coax?

On the old coax we had about 35 watts out from 100 watts input. The new one we have about 90 watts output. Much better!

Great picture! They remind me of this video of replacing a beacon bulb on a 1768 ft. tower. Thanks for sharing.

I saw one like that - may be the same one (can't see it right now - I'm at work and all videos are blocked). If it is the same one, I was cringing just watching it!

I'm glad there are OTHER people who like to do that.

Jumping out of perfectly good airplanes is much 'easier' than climbing a tower. On a tower, you are 'too close' to the ground.

I could never understand why someone would jump out of a perfectly good airplane? But scaling a 1,768 foot tower to change a beacon bulb, I would want at lease a base jumper's chute.

Thanks, but no thanks. Not enough money in it for me.

I have to agree, jumping out of airplanes is much safer, as you usually have a Reserve Chute.

Former Paratrooper (507th PIR), and 2/75 Rangers w/ 632 career jumps..... w/ T-10 main chutes.

Who said they were perfectly good airplanes anyhow? LMAO!!!!

Just a figure of speech.

(Cherry Jumper 3 T-10's, 2 MC-1's, plus some sport jumps at an obscure Az drop zone between Phoenix and Tuscon.)

They were still flying under power and control, weren't they? ....perfectly good airplanes, then.

Or, were you jumping from a step ladder?

That sounds terrible. I'm sure you get used to it but the first time climbing it I'd be close to sick. I get a little nervous just climbing the fire towers at the top of mountains in the catskills.

Good job, sounds like the old cables issues were causing at lot of loss, 7/8 should be about 1.4dB/100M as against ~0.8dB/100M for the new cable. Done a fair bit of hardline work on commercial and amateur repeaters here. But as our o/p power is very restricted 10-15watts ERP we don't have power handling issues as such. Now with so many hams going digital, and the loss of operating sites/licensing restrictions due to car makers using 433Mhz key fobs I don't even bother carrying my dual bander handie anymore.
