-4 Update ….PropMan
Lots happening today! Opening SA an see David Anders article on cooling, finished riveting F404 together and maiden flight for my Bearhawk LSA.
The article is very informative, made my head spin, hope to use some of the info on my 4 even tho I have a different mission. Waiting on some parts from Vans to finish up the wings. May build the fuse jig while I wait.
All good replies above. Here are some additional pics of where mine is mounted including also a pic of the canopy at full rear extension. Like the others, I don't think placing the antenna behind the rail will work. Just behind the rear passenger area seems to work and be readily accessible. If there is room on top of the instrument panel that could make for a shorter cable run.
RE: Bob Archer antenna. I make my own. Follow the instructions in the AeroElectric bible but change the dimensions to take full advantage of whatever wingtip width you have. The more of the antenna extending outboard of the last wing rib the better to enhance antenna range. I typically get VOR well past 100nmi and LOC/GS beyond practical range. You will need to borrow and antenna analizer to get the now modified antenna lengths correct. Borrow one and while you have it ring out your comm antennas and feed line to make sure all is good.
Using the same photo, you can see the black split conduit attached to the outside eleement. That conduit rides in the wingtip far inside edge. It does not flop around.
Also note the antenna is mounted more aft of the leading edge than shown in the Archer instructions. This moves it way from potential RFI created by the nav & strobe LEDs. No reason to cram it forward at all - and do not run lighting wires along the antenna element.

Reaming the Engine Mount
I’m building a taildragger and I’m a bit confused about the reaming progress. Firstly, the holes in the firewall have already been reamed to 3/8” back in chapter 27 when I attached the firewall. This is the instructions in the taildragger page 40B-2: So this leads me to think I have to...

The Wings Are On … For Good!
With 54 of 58 bolts installed (the last four end up behind the side consoles, and after a full day crouching in the cockpit, I was happy to leave them for tomorrow….), the wings are on the Rocket for good - forever! Only old-timers (those who have built -3’s, -4’s, -6’s, or Rockets will really...

Third time is the Charm. My 4 Will get done!
Third time is the charm! I've started this project too many times not to finish, with the first two kits being sold for various reasons, and I keep getting sellers remorse. This one is gonna fly. My mission has been refined to a point that make this 4 very old school with bits of Rocket. Two...

GTN GPS Antenna just aft of the canopy rail?
Hello! I'm (still) waiting on backordered parts, so I don't have the ability to actually roll my canopy frame on the mounts. I'm finishing up the last bit of wiring - antennas! Would this location conflict with the frame at all as it moves? Or is it safe to place the antenna here? I can't...

Bob archer antenna
Gator & Pilot 8 Here's mine a few years ago while under construction. The red tape held the antenna in place while under construction and was replaced with a layer of 5 oz. fiberglass a few days after this photo was taken. Aeroled strobe/nav ligt was used just forward of the antenna under the...
